Page 5: Introduction
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... -
Page 6: Dust Explosions
The user shall be fully conversant with the provisions of NFPA and shall comply in full with all of its requirements. By its very nature AAF equipment is intended to be used to capture airborne particulate matter, otherwise known as dust. There are various methods for dealing with a dust explosion in a dust collector. -
Page 7: Electrical Hazards
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. -

Page 13: Site Preparation
SITE PREPARATION 8.1 Locating equipment The dust collector site location must take into account the wind and seismic loadings. See collector specifications to ensure proper site location. The collector is suitable for indoor and outdoor applications. Ensure proper equipment and accessories are equipped on the OptiFlo RC for such installations. The collector can be located on a foundation (by others) or on structural framing (by others). -
Page 14: Assembly And Installation
Flanged joints exist where housing modules must be bolted together and where hoppers are bolted to the lower faces of the housing. In most cases, AAF will provide sufficient tubes of sealant which must be applied to one of the opposing faces just prior to the faces being brought together. -
Page 15: Products Shipped In Multiple Modular Assemblies
Level the hopper once installed. 9.2.4.3 Collector Housing Apply sealant (supplied by AAF) to the upper flanges of the hopper(s) ensuring the sealant circles around each bolt hole. Lift the housing module(s) using its lifting lugs and lower into position onto the hoppers so that the holes in the matching flanges correctly align. -
Page 16: Installing The Access Components
Refer to the electrical drawings issued with the general arrangement drawing. When the AAF Control Center or Pressure Demand controller is to be used, select a location for fixing the enclosure within 15ft of the static taps located on either of the OptiFlo RC side panels. -
Page 17: Installation Of Accessories
1. Provide safe access to the porthole doors at the front of the OptiFlo RC. 2. Open the filter access door by turning the knob counter clockwise until the door is loose. Be sure to support the door during opening so it does not fall or drop and become damaged. - Page 18 To power up the DCT controller, connect power line to L1 and L2. Control Wiring must be field installed between the solenoid valves and the pulse output terminals as shown on the electrical connection diagram that is supplied with the specific OptiFlo RC collector ordered.

When setting up the DCT, the “high limit” is normally set at 3” w.g. and the “low limit” is normally set up at 2” w.g. Different applications require different settings. Please contact AAF International for assistance. For troubleshooting and for further information, see the Dwyer DCT controller IOM. -
Page 20: Explosion Vents
EXPLOSION VENTS The following only applies to AAF-supplied explosion vents. Additional and/or different steps, equipment, etc. may be needed for vents and other equipment not supplied by AAF. Further, the following is a non-exhaustive list of recommendations, and users must carefully read, among other things, the manufacturer’s explosion vent guide for further instructions. -
Page 21: Explosion Vent Burst Sensor
10.3 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. -
Page 22: Servicing
10.4 Servicing Explosion vents should be inspected regularly to confirm physical and operational condition. Reference the manufacture’s recommendations and consult with the authorities with jurisdiction. Replace any damaged or worn parts immediately. 10.5 Safety distance The material discharged during a vented explosion must be directed outdoors. Locating equipment with explosion vents outdoors is always recommended. -
Page 23: Normal Operation
The OptiFlo RC is assumed to be part of a system that will include a fan and possibly other components, supplied by AAF or other companies. For successful operation of the OptiFlo RC, it must be ensured that: A suitable, dry compressed air supply to the compressed air manifold(s) is available and connected to the collector at all times. -
Page 24: Initial Weekly Maintenance
Effective cleaning is reliant upon pulse frequency, duration and pulse compressed air pressure. The pulse duration is pre-set at 100 milliseconds. DO NOT change the factory setting without contacting an AAF International representative. -
Page 25: Six Months
Check the dust disposal equipment for correct operation and comply with any lubrication or maintenance instructions in the relevant manufactures’ instructions. If an AAF barrel top adapter is installed, check the condition of the flexible, or hard pipe, sleeve and replace if showing signs of wear or if torn. -
Page 26: Cartridge Removal And Installation
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. Inspect all gaskets and panels for possible leak points. Replace gaskets and re-caulk panels as necessary. -
Page 27: Accessories
Re-open the compressed air to operating pressure (90 psi). 12.6 Accessories AAF accessories should be inspected for wear or damage on the same interval as the cartridges. Any accessory equipment should follow the maintenance schedule that is included in the manufacturer’s IOM. - Page 28 Excess airflow and/or excessive dust loading will cause high differential pressure. Measure the airflow, and measure, or estimate the inlet dust loading. Compare with the original design criteria.

Page 29: Visible Discharge (Emission To Atmosphere)
Cartridges have a finite life. Eventually the dust can become deeply embedded or adhere to the media so that even the most vigorous pulsing will not recover an acceptable permeability. Replace with a new set of AAF cartridges. 13.2 Visible Discharge (emission to atmosphere) -
