2.2 Safe working practices and staff training AAF International is fully committed to the safety of its employees and those of its customers. In this spirit the following guidelines are offered for the consideration of those responsible: 2015 American Air Filter Company, Inc.
Except as otherwise expressly provided in writing, AAF makes no representation or warranty in connection with explosion hazard equipment, including, but not limited to, the necessity or effectiveness of explosion hazard equipment or to the design, installation, operation, and performance of such equipment.

For instance, if an explosion suppression system is being supplied by parties other than AAF, it is incumbent on the user to ensure that the dust collection equipment has been ordered to resist the internal pressure defined by the suppression equipment supplier.
2.5 Rotating equipment The FabriPulse M can include a fan which is installed on the top of the dust collector, either on top of the collector or as an integral fan. The fan wheel rotates at a nominal speed of 3,600 rpm and has the potential to cause severe injury. The fan wheel could be accessed from inside the cabinet through the air inlet if the pulse pipes are removed, and from outside the cabinet through the fan discharge.
3.2 Purpose and intended use The FabriPulse M is intended to be used for relatively dry nuisance dusts, with loadings generally less than 8 grains per cubic foot (8 gr/ft ).
Each header of the FabriPulse M comes with 42 bags. The size nomenclature for the FabriPulse M is the length of the bag, followed by the total number of bags, followed by the total square feet of available media. For instance, the 6-336-1200 means that the collector has 6 foot bags, has 336 total bags, and a total media area of 1200 square feet.
PRODUCT SHIPMENT Unless otherwise defined in the purchase order and agreed by AAF, the FabriPulse M is arranged and palletized for domestic transit and shipped FOB the AAF factory. The method of shipment will be as specified in the customer’s purchase order to AAF.
Any missing goods should be noted on the delivery receipt and the carrier notified immediately. Contact AAF International for claim filing procedure. FOR ASSISTANCE: Contact AAF International at 1-800-477-1214. Have the AAF control number available. The control number can be found on the shipping papers. UNLOADING AND HANDLING 6.1 Unloading and lifting into position...
Safety legislation. STORAGE AND PROTECTION In the event the FabriPulse M is not placed in service within 30 days after receipt, the filter bags must be removed and stored in a clean, dry place to prevent possible moisture accumulation in the media.
Check the drawings of the specific FabriPulse M ordered for the dust collector weight. 8.3 Anchoring See the specific FabriPulse M collector drawing for anchor bolt location. Anchor bolts must extend at least 1.75 inches above the foundation. The collector...
9.2 Assembling and installing the structure 9.2.1 Products shipped as a single assembly All of the FabriPulse M dust collectors are shipped factory assembled requiring only: • Assembly of hopper section to housing on sizes 336 and 420 • Field bolting of the legs and braces •...
2 connection taps on the pulse controller and the other ends to the static taps located on the side wall of the FabriPulse M. These plastic pipes allow the pulse controller to measure and display the differential pressure that exists between the clean air plenum and dirty side plenum.
The standard pulse control supplied with the FabriPulse M is the DCT-1010 (or 1022) Dust Collector Timer Controller. This pulse controller is used for on- demand or continuous cleaning applications.

FabriPulse M collector ordered. If the collector has been factory wired as an option, the solenoids are prewired to a junction box with a terminal strip.
The FabriPulse M is not designed to support ductwork. One way of ensuring no loads from the ductwork is transferred to the collector, flexible connections can be provided between the collector’s inlet and outlet flanges and process ducting.
Ensure no damage has been done to the explosion vent during shipping or handling. The FabriPulse M will have a frame constructed as part of the unit where the explosion vent is mounted. The number of explosion vents and location of the explosion vent will be detailed on the collector drawing.
Explosion Vent Burst Sensor All standard explosion vents come with a burst sensor. This can be connected to an AAF Control Center or to the customer’s controls to shut down the unit when an event occurs. The magnetic sensor is suitable for use in Class I and II, Division I, Groups A to G.
The procedure should also be followed after installing new bags in the unit. 11.2 Normal operation An understanding of the design and operating principle of the FabriPulse M is essential for effective operation and maintenance. Knowledge of the collector nomenclature is necessary so that parts can be easily identified and located.
Check the dust disposal equipment for correct operation and comply with any lubrication or maintenance instructions in the relevant manufactures’ instructions. If AAF barrel top adapter mechanism is installed, check the condition of the flexible sleeve and replace if showing signs of wear or if torn.
Remove the used solenoids from within the solenoid box enclosure and replace them with new items if required. NOTE: AAF recommends having a spare set of diaphragm and solenoid kits available at all times. 12.5 Filter removal and installation See section 9.2.7 for further information.
12.7 Accessories AAF accessories should be inspected for wear or damage on the same interval as the bags. Any accessory equipment should follow the maintenance schedule that is included in the manufacturer’s IOM. TROUBLESHOOTING 13.1 High Differential Pressure Reading Improper Control Operation Check the wiring, fuses, and setting of pulse duration and interval.
13.2 Visible Discharge Improperly installed or damaged bags Check for holes or rips in bags. Replace damaged bags with AAF replacement bags. Reseal bags as necessary. Improper sealing of the header Vacuum dust from the clean air side of the collector. Inspect the header seal.
