The MAXIPLY unit may have between 170 to 700 sq. ft of filter depending on the model selected. Figure 1 Figure 1 : Presentation DMP-170S PRESENTATION DMP-170S... -
Page 5: Each Maxiply Unit Includes
Multiple pocket type dust collector 3.1 Each MAXIPLY unit includes: • Welded steel hopper. • 25 gallon dust bin. • Quick-clip dust bin removal system. • 1 polyester filter envelope having between 170 to 700 sq. ft of filter surface. Maximum air to cloth ratio to be 10:1. • Various hardware. • Handle for filter shaker cleaning action. • Aluminum direct drive radial type fan/motor assembly. • 3 step paint preparation: degreasing, primer and polyurethane base paint final coat. The MAXIPLY unit is shipped partly assembled and some components will require field assembly. This will allow the dust collector to be assembled in an area where the access doors are narrow where fully assembled unit would not fit through the doorway frame. The electrical connection of the fan motor must be performed by a qualified electrician. NORMAL USE AS PER NFPA 664 The MAXIPLY unit is designed to filter harmful dusts from the air resulting from a fabrication process. Each MAXIPLY dust collector is built based on the request and information supplied by the customer for a given application and should not be used for any other application unless approved by A.Q.C., Inc. The dust collector should be used at intervals in order for the filter envelope to be... -
Page 6: Functioning
Multiple pocket type dust collector OPERATION During normal use, the MAXIPLY unit receives dust filled air from the blower toward the collector inlet. The smaller particles are pushed toward the filter envelope and the larger particles fall into the dust storage compartment. The smaller particles are stored into the filter envelope and clean air is exhausted through the four (4) opened sides of the filter cabinet. 5.1 Cleaning of the filter envelope When the collector is shut down, the operator must wait until the motor has stopped turning completely. The cleaning is made by shaking by hand the pockets of the filter bag. 5.2 Manual shaker (optional) When the collector is shut down, the operator must wait until the motor has stopped turning completely. The cleaning is made by vigorously shaking the handle on the side of the unit. INSTALLATION 6.1 Inspection of the material The MAXIPLY unit is shipped on one (1) or multiple skids. Proceed with a visual inspection upon receiving the material for any damages or missing skid(s). Note: if damages are apparent upon receiving the material, indicate so on receiving slip (freight waybill) and confirm by having the truck driver sign the waybill with any discrepancy. A.Q.C takes photos of material prior to shipping. Generally, shipment includes a skid for the collector cabinet and another one for the dust storage system. Other optional devices are shipped on separate skids. 6.2 Area of installation 1. The area chosen to install the collector should be able to support its weight, its accessories, dust storage system and ventilation ducting. The construction of a solid flat surface such as a concrete pad may be needed. 2. Position the dust collector in a way to have access to the blower and filter envelope. A 12" (0,3 meter) work space is required around the collector for maintenance purposes. Figure 2 12" FREE SPACE 12"... -

Page 13: Ducting Systems
Multiple pocket type dust collector The fan starter is not supplied by A.Q.C. Inc. Contact A.Q.C. Inc. for information on the proper starter for your dust collector. The electrical panel may be installed directly on the Maxiply unit or remote. Once all electrical connections have been completed, switch "ON" the motor and check for proper blower wheel rotation. 7.3 Ducting systems • The dust collector should be installed as close as possible to the machines creating the dust. This is to minimize the length of the ductwork. • If possible, do not install short radius elbows or bends. • Install taps or branches having a 30 degree slope or less. • Do not install straight 90 degree taps (T’s). • Join ductwork and branches using self tapping screws and silicone. Preferred ducting system is clamp-on type not requiring any screws causing possible jams and dust build-up at the screws. 8 START-UP 8.1 Check list Before starting the dust collector for the first time, the steps listed below should be followed to ensure the collector will work properly. • Remove all objects in the vicinity of the collector inlet and outlet. • Ensure all accessories and optional equipment are secured and installed correctly. 8.2 Shaker system • Check if the upper filter frame is well in place and fastened correctly. 8.3 Electrical connections WARNING! The electrical connection must be performed by a certified... -
Page 14: Start/Stop Procedure
Multiple pocket type dust collector • Check if all electrical connections are watertight and proper electrical current is available. • Check if all remote controls (if supplied) are connected to the control panel and all switches are at the "OFF" position. • Supply power to the collector. • Start the fan and shut it "OFF" immediately. Check motor rotation. START/STOP PROCEDURE 9.1 Starting the unit with a new filter envelope Shut inlet and outlet dampers (if installed) at about 50% before starting the unit. Allow a few hours for dust to penetrate the filter envelope before starting the shaker system. This will result in a better filtration efficiency and longer filter envelope lifetime. 9.2 Normal start-up Start the collector and allow dust to enter the unit. 9.3 Shutting the unit OFF Shut down power to the collector and close all inlet and outlet dampers so that dust does not flow back into the unit. You may now access the collector for inspection, drum change or drum empty out and/or filter envelope replacement. SAFETY MEASURES 10.1 Workers/Staff Any maintenance on the collector should be accomplished by a minimum of two (2) workers. When finished, retrieve all tools inside the collector. All maintenance staff should wear protective clothing or apparatus such as goggles, gloves, breathing equipment or such devices before working inside the collector. -
Page 15: Electrical Components
Multiple pocket type dust collector 10.2 Electrical components To avoid injuries, all electrical components must be shut off prior to inspection or servicing the unit. This procedure includes getting access to the filter section. 10.3 Anchor All sections of the collector should be firmly anchored to the floor in order to prevent tipping of the unit should an explosion occur or by accidently hitting the unit with moving equipment such as lift trucks. 10.4 Processes creating spark This dust collector is designed for wood dust only. MAINTENANCE WARNING! Refer to the safety measures section before proceeding with the inspection or maintenance of the dust collector. A scheduled preventive maintenance program will reduce downtime situations and increase lifetime of the unit. Charts shown in this chapter refer to maintenance and procedures related in solving malfunction. Timers and delays may be modified with conclusive experimenting of the system on a particular application. 11.1 Replacing the filter envelope The lifetime of the filter envelope is directly linked to its resistance to the dust filtered and does not necessarily require a regular filter replacement. However, if the filter envelope is torn or punctured, it needs to be replaced as soon as possible. -
