Notes on Using this Pamphlet:

This pamphlet is presented as a service to systems designers working with medical gas and vacuum inmedical facilities. The design process used in this booklet is detailed in Chapter 1 - Design Process.

This Guide is not in any way intended to be a substitute for a properly qualied engineer, and any pretence tobeing alone sucient for the proper design of any medical gas system is explicitly disclaimed.

It is BeaconMedæs’ intent that this book should only be used as one tool among many by properly qualiedengineers who are in a position by training and experience to know it’s applications and limitations.

You will nd in using the Guide that there are innumerable decisions, judgement calls, and subtleties in thedesign of medical gases which cannot be incorporated in any book, but serve to dramatically emphasize thevalue of the engineer’s expertise.

Introduction

Medical vacuum is, compared to other medical gassource systems, quite straightforward. The mostdicult part of the process comes in the selection of the technology to be used because there are so manycompeting technologies, each with their own appealand it must be said, their own warts. NFPA and CSAstandards have relatively few requirements and thoseare readily met, so the decision becomes a balancingof the clients’s concerns for risk, initial cost vs. lifecycle cost, and maintenance requirements.

Engineers use the term “vacuum”, but cliniciansuse the term “suction”, and if you have occasion tospeak with the clinicians, you’ll nd the terminologysubtlely dierent. In addition, although the averageclinician cannot articulate it, their major concern is ow. It is quite common to have a maintenance man,called to x “poor suction”, plug in a vacuum guageand quite accurately tell the complaining nurse “yougot all I got”. He’s right in terms of vacuum level, butthe nurse is really complaining that she has no ow.

If we are to complete a successful design, we must

grapple this problem all the way through the system.Providing ow is primarily a piping problem whichwe will deal with in Chapter 11, but this distinctionis important to understand because it aects pumpselection as well. Giving a higher ultimate vacuummay be helpful, but it rarely solves a problem of ow.Only fat pipes can do that. Seeking a high vacuumlevel may actually waste our client’s money andprovide no solution to their real problem.

The methods for sizing vacuum sources are alwaysa surprise to new engineers, because there are somany (we present three here) and because the most

commonly used are so poorly documented. TheCGA P-2.1 has been withdrawn by it’s publisher,the Compressed Gas Association. It was essentiallyunchanged since the 1970’s, but there is almostnothing but the patina of age to substantiate thenumbers it contains. The NFPA method was removed from the NFPA 99 because it too was considered outof date. Fortunately, it at least has a research history.We continue to use these two in the US because wehave used them for so long. We know from experiencethat they do work.

The HTM method is published in the HTM 2022standard, and is the method used in the U.K. Wehave included it here as an additional method forcomparison.

Step One: Discovery

1. If existing equipment is to be retainedin service, determine (by actualobservation if possible) the type, size,capacity and current loading. Ensure

the existing equipment is compliant with the currentstandard.

2. Determine the number type and inlet count of alloccupancies in the facility which will receive medicalvacuum inlets.

3. Determine if there are unusual circumstances whichmay increase vacuum use. A classic example is the longterm care facility where wheelchair bound ventilatorpatients are taught to suction their own airway.Suction demand is enormous, because they leave the

suction lines open constantly. A system sized usingtraditional criteria would burn itself out in a matter of months under such a load.

4. Examine the location intended for the exhaust.NFPA mandates the exhaust be outdoors, 3m (10 feet) from any other opening, at a dierent level (usuallylower) than any air intake, and in a location unlikely toblow contaminated air where people are likely to be orwhere it cannot disperse. (Ref. NFPA 99 5.1.3.6.7)

Ensure the exhaust (or the intended location for theexhaust) is located away from all other vents, windows,

and especially away from any intakes (e.g. compressedair intakes, HVAC intakes).

5. Determine a routing for the exhaust piping and noteit on the building drawings.

6. Ensure the intended location for the vacuumplant is adequately ventilated or is air conditioned.The plant will discharge considerable heat into theenclosure, which must be factored in when selectinga pump site, determining the adequacy of ventilation,

or BTU requirements for air conditioning. (BTU data is furnished on the equipment data sheets.)

7. Determine the availability of electrical service.

8. If the vacuum system is not already piped to theintended location, determine the routing for the pipingand note it on the building drawings.

Step Two: Design

Follow directions for laying out pipedmedical gases as found in Chapter 4 of this Guide. This will provide the countof inlets and occupancies which arenecessary for the next steps.

Engineering

Step Three: Plant Sizing

There are several available methods forsizing Vacuum. Three are included inthis Guide: the P-2.1 Method, the NFPAmethod and the HTM 2022 method

used in the U.K.

P-2.1 Method

1. Using the list of occupancies in Detail 6.6, place allof the occupancies in the project into these categoriesbased on best match.

2. Note the counting units assigned to each of thecategories. Where the unit is “room”, you can ignorethe inlet count and simply use the ow listed for eachroom. Where the unit is “Bed”, you can ignore theinlet count and simply count the maximum number of patients in that occupancy. Where the unit is “station”,you should count the number of individual work spaces

or treatment spaces and use the ow listed for each ofthose.

3. When all occupancies have been accounted formultiply by the ow for each and sum all the required ows. Add additional ow for any unusual conditionsand use this sum to select the pump.

4. Go to note below.

NFPA Method

1. Enter the number of inlets based on the occupancieslist in Detail 6.6. Sum all the inlets in “A” occupanciesand all the inlets in “B” occupancies separately. Alsosum all operating rooms, trauma rooms and any otheknown high-demand occupancies.

2. When all occupancies have been accounted for, sumthe total number of “A” inlets. Referencing the graph inDetail 6.5, determine the diversity factor by reading the

number of inlets on the bottom against the diversity onthe left. Plug the result into the following formula:

Number of “A” inlets x 0.25 x Diversity from Detail 6.5.

3. Sum the total number of “B” inlets. Referencing thegraph in Detail 6.5, determine the diversity by readingthe number of inlets on the bottom against the diversityon the left. Plug the result into the following formula:

Number of “B” inlets x 0.25 x Diversity from Detail 6.5.

4. Sum the total number of O.R. and high demandlocations (by rooms). Apply the following formula:

Number of high demand rooms X 1.5.

5. Sum the results of steps 2, 3 and 4 to obtain a totalsystem demand in scfm. This can be used to select asystem.


HTM 2022 Method

1. Take counts by occupancy in the counting units foundin Detail 6.7.1.

2. Insert the count into the formulæ shown for eachoccupancy category.

3. Sum the requirements column for total usage.

elevations, the peak calculated demand from Step 3 should be multipliedby the appropriate correction factoshown in Detail 6.7.2.

This method of correction assumesupsizing the pump to hold as close tothe standard vacuum level (19inHgV)

as possible and represents the ratioof ACFM at sea level vs. the ACFM atthe altitude. If the facility is willing toaccept a lower vacuum level (see theIntroduction), this number (and thuspump size) can be reduced.

Step Five: Compensating for “Futureexpansion”

The idea of adding capacity now foany future requirements is wise, butonly if carefully thought out. It is not

uncommon to see oversized vacuumplants which were originally sized toaccommodate an expansion that neveoccurred or that was scaled back andnever required.

The best method for preparing foanticipated expansion is to select aplant which is adequate for the presentneed in a duplex or triplex system andcan be upsized for the future needby adding additional pumps. When

specifying the unit, require it bepurchased prepared for the addionapump(s) but not populated with thosepumps. A typical specication wouldread:

“provide duplex vacuum plant withtriplex controls ready for a futurethird pump”

Such a system provides an eectivemethod of expanding system capacityis more capital-ecient, and ensures

better operating characteristics.

However, it is vitally important that theintake, electrical service, and systempiping be correctly sized for the entireanticipated capacity, so these largevalues should be used in all calculations

Step Six: Plant Selection

1. Select a preferred technology (see

approximations and should be usedjudiciously. If an existing pump is beingreplaced, the operating characteristics of that system can be an important guage

of likely future use. As an example, if an existing 5 Hp. pump was seen to beadequate, but the sizing tables yieldeda much larger requirement, it might beappropriate to use a smaller compromiseunit as opposed to simply relying on theresults from the sizings.

Step Four: Altitude compensation

If a pump is to be operated at higher

Detail 6.9A Quick Guide to Configurations

VerticalVertical configurations have two Pumps stacked on a single base. This configuration is only suitable fosmaller Pumps or Pumps with very little inherent vibration. It is the most space-efficient of all medicalvacuum configurations, and oil less vertical systems are spectacularly space-efficient.

Stack Mount (SPC)In Stack Mount systems, the Pumps are mounted above one another in a “stacked” configuration. Thereceiver is mounted above the pumps. These systems are typically single point connection style.

Single Point Connection (SPC)In SPC systems, the pumps are mounted on a base which is large enoughto accomodate all the pumps and accessories. The system is factory

piped and wired to a single inlet, outlet and electrical connection. Theycan be partially disassembled in the field for easier handling. Systemsconfigured this way are particularly popular with contractors because of the low labor requirement.

ModularEach pump, and the controls and receiver are mounted on individualbases for easy handling and placement where space is at a premium.These systems are especially well suited for retrofit or replacementsituations. Each module will fit through a standard 3-0 doorframe andcan be handled with a standard pallet jack.

Tank MountThese systems are mounted atop their receivers and use the receivers for support. Insmall sizes they are space efficient and cost effective.

Frame Mount or “with Mounted Tank”These are a variant of the tankmount systems employed with larger systems whichcannot be mounted on the tank itself. The Pumps and accessories are mounted on aframe with the tank slung underneath.

Detail 6.8 for basic comparisons). More specicassistance in selecting a technology may be obtained bycontacting your local BeaconMedæs representative.

2. Choose a horsepower from the preferred technologywith the capacity nearest to (but typically greater than)the peak calculated demand (Ref. Detail 6.10).

3. Note that for some technologies there is more than

one plant architecture (see Detail 6.9 for an explanationof the dierent architectures). Where more than onearchitecture is available, choose the one best suited tothe site conditions. If in doubt as to the best systemarchitecture for a particular situation, contact yourBeaconMedæs representative for assistance.

4. Reference the system information (SSB sheet) fothe particular system selected (Ref. Details 6.13-6.17

2. Place the equipment in elevation views as appropriate.

3. On the plans, nalize the routing for the exhaust.

4. Size the exhaust piping. A quick reference for exhaustsizing is contained in Detail 6.11. The sizing process isiterative:

a. Start with the total actual length of piping, andbased on Detail 6.11 make an estimate for the linesize.

b. Using your estimated size, add equivalent lengths for the ttings employed.

c. Check the size is still acceptable at the newequivalent length. If not, re-estimate the next largersize and repeat the steps above.

The line may also be more accurately sized by actualcalculation. Intake piping must be sized to induce

no more than 100mm (4 inches) water columnbackpressure at the pump outlet when all pumps

are running. (use total capacity for thiscalculation not NFPA capacity).

For unusual lengths or othercircumstances, contact yourBeaconMedæs representative forassistance.

5. Finalize the connection to the distribution piping andsize the system piping (see Chapter 4 of this Guide)

Step Eight: Specication

1. In section 2.3 D of the Guide specication, selectthe sections appropriate to the technology and systemarchitecture desired.

2. Write into the specication any exceptionalrequirements (soft starters, etc.).

3. Schedule on the drawings the vacuum plant selected.Schedule at least:

a. The capacity per pump (per NFPA) and total system.b. Horsepower or kW per compressor.c. Voltage, Hz, and phase desired.

Notes on the System Selection Tables (Detail 6.13-6.17)

These tables represent standard systems andcongurations and do not represent all congurations.

In particular:

Envelope dimensions do not include maintenancespace. BeaconMedæs recommends 92 cm. (36in.) on all sides, but less space may be possiblewith an understanding of the system maintenancerequirements. In all cases the National Electrical Coderequires a minimum clearance of 914 mm (36 in.) in front of the control cabinet.

Contact your BeaconMedæs representative if you needto t the systems in smaller spaces.

All systems listed have the standard receivers. Largerreceivers usually change the envelope dimensions.

The Modular system’s envelope dimensions shownrepresent a typical arrangement for minimum oor space. However, modular systems are easilylocated wherever appropriate, which will change thedimensional requirements. Envelope dimensions formodular systems should be used only as rough guides.

More details on all dimensions will be found on theSSB sheets for the system selected, and the SSB sheetshould be consulted when doing nal layout.
