Exterior-mount variable- or fixed-speed Auto Draft® inducers can reduce vent diameters up to 50%, overcome convoluted vent layouts, and shorten stack height above the roof line, says the company. The units induce negative pressure throughout the vent system to overcome high static pressure losses associated with long horizontal vent runs and reduced vent diameters. The inducers can be used for sidewall or rooftop venting. Features include heavy-duty 5052 aluminum housing; high-temperature, corrosion-resistant Ryton® PPS coating; backward-inclined, self-cleaning, 304 stainless steel impeller; auxiliary motor-cooling fan; and a permanently lubricated ball bearing motor. The inducers can be used with the CPC-2 constant-pressure controller to automatically regulate fan speed based on a user-set manifold/vent pressure. Up to 14 appliances can be interlocked to a single controller.
