I. DESCRIPTION

The model PFB-1600 is a cart mounted HEPA Filtration Module which includes an air inlet transition, filter housing, filter elements, outlet transition, and a blower/motor assembly. The PFB-1600 blower is capable of flow rates ranging from 1015 CFM at 9 inches S.P to 1720 CFM at 1 inch S.P. The blower is integrally mounted, direct drive and is connected to the outlet transition with a flexible boot. The filter blower assembly is mounted on a heavy duty cart that is equipped with rigid and swivel casters and a push handle. The filter housings, transitions, and cart are fabricated from 304SS. Electric power is controlled by a magnetic starter with overload protection. The starter has a IP66 enclosure and is equipped with “Start-Stop” pushbuttons. The motor and starter are configured and pre-wired to accept 230 or 460 VAC, 60 Hz, 3 phase power.

The filter housing consists of one Bag-In/Bag-Out (BI/BO) prefilter and HEPA filter assembly. Each assembly incorporates separate BI/BO chambers for a prefilter and HEPA filter (two chambers total, each with its own access door for filter change-outs). The inlet plenum is equipped with two 8 inch diameter flex duct connections. Each connection contains a flow control damper which can be locked in any desired position. The discharge adapter accommodates 8” diameter flex duct and is fitted with a guard to prevent access to the blower wheel.

To determine filter loading, differential pressure is monitored across both the prefilter and HEPA filter independently. Each filter has its own permanently mounted Magnehelic differential pressure gage (2 gages total).

V. OPERATING INSTRUCTIONS



A. Prerequisites

1. Prior to first-time use, ensure prefilters and HEPA filters are installed per instructions.

Ensure that change-out bags are in place.

2. If required by site procedures, ensure that aerosol-challenge testing of in-place HEPA

filters is current.

3. Inspect all components/hardware for damage. Particular attention should be given to

HEPA filters.

4. Check differential pressure gage for zero set point. Zero as necessary.

5. Ensure blower motor controller is in "OFF" position. Check all electrical connections

and cables for damage.

6. Ensure that power supply voltage and phase match unit labels.

7. Energize the blower and verify correct motor rotation. If motor is rotating backwards,

immediately de-energize and correct phase rotation before re-energizing.

B. Cautions

1. Perform frequent gamma surveys of filter housing, especially immediately following

initial system start-up. Radiation dose rates may increase rapidly.

2. Whenever possible, reduce to a minimum the number of bends (especially sharp

bends) in flexible ducting runs to avoid unnecessary pressure drops through the

system.

C. Operation

1. Position the ventilation unit as desired.

2. Configure dampers and duct to provide the desired flow path during system operation.

At least one damper must be open at all times while unit is operating to prevent

damage to filter elements.

3. Adjust inlet dampers as necessary to meet the desired ventilation requirements.

4. Note the initial reading on the differential pressure gages once the desired system flow

has been achieved. These initial readings will be used to determine when filter

changing is required.



VI. FILTER CHANGE

Filter change requirements are generally dictated by three conditions: radiation levels within the filter housing, ventilation flow requirements reduced by filter loading, or excessive differential pressure. Site radiological procedures will govern when radiological conditions warrant filter change-out. As the filters load with dirt, the system flow rate will begin to fall. Depending upon the application, the flow rate may fall below acceptable levels before the filters become fully loaded with dirt. In this case, the actual flow rate will dictate when the filters are changed. High differential pressure (DP) across the prefilters or HEPA filters indicate that the filters are dirty. Filter change-out should be performed when (or before) the DP across the prefilters increases to approximately 2" - 3" wg pressure or the HEPA filters to approximately 4" - 5" wg pressure. The prefilter should be changed out more frequently to help preserve the HEPA filter. Applications with conditions of high amounts of dust and debris will require more frequent filter changes than low airborne dust conditions. The prefilter should not be operated above 3” wg or the HEPA filter above 5” for an extended period.

NOTE: Prior to filter change-out, survey the filter assemblies to determine radiation and contamination levels. Results will indicate protective measures to be taken.

















MAINTENANCE ITEM FREQUENCY

Verify proper motor rotation. Upon wiring/rewiring motor

connections

Check DP set point for zero set point. At start up

Most smaller motors have sealed bearings that never require re-lubrication for the life

of the motor. For any motors with grease fittings, consult the motor manufacturers

recommendations with reference to lubrication frequency and the type of grease that

should be used.

As required

Change filters. As stated in Sec. VI

VII. TROUBLESHOOTING GUIDE

The following table offers a guide for the more common problems that can be encountered. As with all machinery disconnect the power before servicing or opening the electrical components.

VIII. PREVENTIVE MAINTENANCE

This portable filtration module requires very little preventive maintenance. The following table provides a list of those items that require checking as well as a recommended frequency.

SYMPTOM ACTION

Unit won't start 1. Reset starter by depressing stop button and then restarting.

2. Make sure unit is electrically connected.

3. Check circuit breaker on circuit that powers the unit.

4. Check connections in starter.

5. Verify that overload heaters are installed correctly.

6. Verify connection is satisfactory and that coil is operating.

DP gage not on zero when

system is not running

1. Re-zero gage by turning set screw on the face of gage.

2. If gage does not zero, replace.

DP gage does not move when

machine is started

1. Check to ensure that the "HI" side of the Prefilter gage is plumbed to the

upstream side of the Prefilter and the "HI" side of the HEPA gage is plumbed to the

upstream side of the HEPA.

2. Make sure nothing is obstructing the inlet plenum.

3. Replace the gage.

Lower than expected flow 1. Verify correct motor rotation and correct if necessary.

2. Excessive resistance to flow caused by flow restrictions, added duct runs, or filter

loading.
