DRYER DUCT BOOSTER • 5 year no lint, no clog, no maintenance warranty

The Dryer Duct Booster should be used on dryer venting in excess of 25’ equivalent length (90° elbows equal 5’ equivalent length). Vent runs in excess of 25’ equivalent length cause excessive drying time, excessive energy use and increased lint build-up in the venting. The Dryer Duct Booster maintains the proper exhaust velocity in dryer vent runs up to 100 equiv- alent feet to optimize dryer performance. Booster motor is mounted outside the air steam for maximum motor life and the “Lint Blitzer” blower wheel is guaranteed not to clog with lint. Booster activated by pressure sensing switch and can be mounted vertically or horizontally. 4” extended duct connections.

VARIABLE SPEED AUTO-DRAFT® INDUCERS

• Commercial multiple appliance venting systems from 500 MBH-6000 MBH. • Variable speed inducer matches draft to fluctuating flue gas volume. • Boilers and Water Heaters maintain ultimate, “lab-condition” fuel efficiency. • Automatically reacts to wind and building pressure fluctuations. • May reduce vent pipe diameter by over 50%, reducing installation expenses. • Improve building aesthetics by eliminating unsightly vertical chimney extensions • May be mounted on roof top or side wall.

Exterior mount Auto-Draft® Inducers are capable of overcoming high static pressure losses associated with long horizontal vent runs and reduced vent diameters. They induce a negative pressure throughout the vent system. Both new and retrofit installations benefit from the interlocked, controlled draft provided by Auto-Draft® Inducers.

SYSTEM COMPONENTS:

• Auto-Draft® Inducer - Variable speed, Ryton® coated, Air-injection cooled motor.

• Controller CPC-3 - Microprocessor based with user programmable interface.

• Motor Driver VFD - 220 VAC three-phase, varies both voltage and frequency. • Pressure Transducer TD-2 - Guarantees exact system draft every cycle. • Balancing Damper - Provides precise control of heater flue outlet draft.

These Auto-Draft® Inducers are capable of overcoming high static pressure losses associated with long horizontal vent runs and reduced vent diameters. They induce a negative pressure throughout the vent system. Both new and retrofit installations benefit from the interlocked,controlled draft provided by Auto-Draft® Inducers. Variable Speed Combustion Air Systems are also available by special order.
