I. DESCRIPTION

The model PFB-2500 is a cart mounted HEPA Filtration Module which includes an air inlet transition, filter housing and filter elements, and air outlet transition, and a blower/motor assembly. The PFB-2500 blower is capable of flow rates ranging from 1900 CFM at 7 inches S.P to 2750 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 two (stacked vertically) Bag-In/Bag-Out (BI/BO) prefilter and HEPA filter assemblies. Each assembly incorporates separate BI/BO chambers for prefilters and HEPA filters (four chambers total, each with its own access door for filter change-outs). The inlet plenum is equipped with four 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 prefilters and HEPA filters. Each filter pair has its own permanently mounted Magnehelic differential pressure gage (2 gages total).

V. OPERATING INSTRUCTIONS



A. Prerequisites

1. Inspect all components/hardware for damage. Ensure the filters have been installed.

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

3. Ensure blower motor controller is in “OFF” position. Check all electrical connections

and cables for damage.

B. Cautions

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

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

2. Where bends in flexible ducting runs are required to suit working configurations, avoid

sharp bends. The number of bends should be kept to a minimum to minimize pressure

drops through the system.

C. Operation

1. Arrange unit in the configuration desired for ventilation supply.

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

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

3. Adjust duct dampers as necessary to provide ventilation requirements.

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

has been achieved. This information will be used to determine when filter changing is

required.



VI. FILTER CHANGE-OUT 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 pre filter 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.

















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 sys-

tem 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 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.

MAINTENANCE ITEM FREQUENCY

Verify proper motor rotation Upon wiring/rewiring motor connections

Check DP set point for zero set point At start up

Lubricate motor in accordance with manufacturers instructions As required

Change filters As stated in Sec. VI
