RE: WIDC – ROUGH-INS FOR DUST COLLECTOR SYSTEM
1. Revise supply and return ductwork distribution in UNBC Lab as indicated on the attached drawing to accommodate additional dust collector ductwork.
2. Provide dust collector ductwork distribution with rough-ins for future connections to woodworking machines inside UNBC Lab and to the future dust collector outside the building as per the attached drawing.
Rough-in connections for future woodworking machines shall be terminated at high level below the suspended ceiling. Rough-in connection for future dust collector shall be capped at high level on the outside wall.
3. The rough-in connections for future woodworking machines shall include the following:
.1 150 (6”) diameter rough-in for future planer (required exhaust: 378l/s or 800cfm) .2 125 (5”) diameter rough-in for future table saw (required exhaust: 260l/s or
550cfm) .3 125 (5”) diameter rough-in for future jointer (required exhaust: 260l/s or 550cfm) .4 100 (4”) diameter rough-in for future band saw (required exhaust: 165l/s or
350cfm) .5 125 (5”) diameter rough-in for future mitre saw (required exhaust: 260l/s or
550cfm) .6 100 (4”) diameter rough-in for future CNC router (required exhaust: 165l/s or
350cfm) .7 150 (6”) diameter rough-in for future floor sweep

4. Future dust collector shall be equal to Murphy model MKAW-400-2D with EA-1 13/C13 fan assembly (10hp, 208/3/60), air flow-1490l/s (3150cfm), TSP-2500Pa (10”), shaker motor (1/2hp, 208/3/60), filter area-37m² (400ft²), c/w pre-wired control panel (inside building), inlet blowback damper, top mounted explosion relief damper, inline discharge silencer and two 170l (45gal) drums with castors.
The future dust collector will be located outside the building as indicated on the attached drawing.
5. Dust collecting ductwork shall be round spiral lockseam duct fabricated from G60 galvanized steel to ASTM A653 and A924. Ducts up to 200 (8”) diameter shall be 22gauge and ducts 225 (9”) to 300 (12”) diameter shall be 20gauge.
Longitudinal seams shall be lapped 25 (1”) and riveted on 75 (3”) centres and then welded airtight. Girth joints shall be lapped 25 (1”) with the inner lap in the direction of airflow, riveted on 75 (3”) centres and welded airtight. High pressure gasketted flange connections are an acceptable alternative.
Elbows shall be minimum two gauges heavier than duct of equal diameter and shall have a minimum inside throat radius of two pipe diameters. Elbows 150 (6”) diameter and less shall be constructed of at least five sections. Elbows over 150 (6”) diameter shall be constructed of at least seven sections. All elbow sections shall be welded. Prefabricated smooth tube elbows are acceptable.
Ductwork shall be securely hung and anchored from the structure at maximum 2400 (8’) and at all elbows and drops. No two branches shall enter the main duct diametrically opposite.
Cleanouts shall be provided where indicated on the drawing. Cleanouts shall be fitted with gaskets, handles and locking devices.
