Wall Fans manufactured by experts!

Direct-drive and belt-drive wall fan are available in centrifugal wall fan construction and axial propeller fan construction. This is an extremely quiet general exhaust, or supply ventilator fan. When supplied with filter package it is used as ambient make-up air fan. Recommended for industrial and commercial applications such as stores, laboratories, offices, agricultural green houses, warehouses, industrial buildings; and in public meeting areas such as churches, auditoriums and theatres for the removal of large volumes of air with low power output. Designed for ease of maintenance and low operating cost combined with quiet operation and low visibility. Available sizes vary from 6 to 84 inches of diameter of the fan prop. Capacity: up to 105,000 CFM. Pressure: up to 2.5 inches of WG.

Wall fans construction features a heavy gauge steel panel with steel frame supports and deep-spun venturi orifice. The Q-wheel is designed for applications where exceptionally low sound levels are required. Four and six bladed die formed fixed pitch propellers are statically and dynamically balanced and are designed for general ventilation fan applications. Cast aluminum adjustable pitch propellers are intended for industrial air ventilation applications and allow for flow adjustment.

Drive mechanism Direct drive ventilator models have propeller connected directly to the motor shaft for minimal wear and maintenance. Belt-drive fan models are equipped with standard fixed, or adjustable single and multiple belts, with variable pitch cast iron pulley for adjusting fan speed. A motor slide base allows for belt tension adjustment. Belts are oil resistant and are not static conducting. Heavy-duty pillow-block bearings with cast iron housings are self-aligning and relubricable , with zerk fittings with extended bearing lube lines. Motors are of totally enclosed (TEFC, or TEAO) type. Explosion proof motors, severy duty motors, IEEE841 motors, mill and chemical duty motors, and special motors are available upon request. All motor brands are UL and CSA certifed and serviced worldwide.

Ventilator Options and Accessories: Wall Housing / Wall Cabinet / Wall Sleeve of galvanized steel is available for convenient mounting and proper spacing of shutters. Automatic and Motor-Operated Fan Shutters are recommended for weather protection and to prevent backdraft when power supply is off. Motorized fan shutters are available for opening/closing action on all air supply applications. Safety Guards are available in motor-side configuration and blade-side configuration. Safety cage is available for total enclosing of the panel fan. All safety guards meet OSHA requirements. Special protective coatings and alloys (aluminum, or stainless) are available upon request. All wall fans have epoxy coating as a standard. Safety Disconnect Switches cut power to motor for servicing of the unit. They are mounted adjacent to fan panel. Fan speed controller provides capability to change performance and speed ranging from 0 % to 100 % of fan capacity for fine-tuning and balancing of the ventilation system.

All ventilator models wall fans bear the AMCA Certified Ratings Seal.

CBC Tri-Lobe Positive Displacement Blowers, due to rotor tips disposed at 120º on each rotor, cause the rotor set to be much more resistant to angular deflection along it's length, than two lobed rotor sets, which have lobe tips disposed at 180º each - this extra "stiffness" provides less deflection at any load, thus minimizing possible rotor contact with both the cylinder and it's sister rotor during operation.

CBC Positive Displacement Blowers (of the "Roots" type design)  are high pressure machines designed for wide variety of applications:

- Pneumatic conveying of bulk materials

- Pressurized aeration of basins in sewage treatment plants

- Filter flushing blowers in drinking water production plant

- Steel production - application in direct-reduction plants.

High vacuum boosters - equipped with special shaft seals.

Conveying of pratically all gases found in the chemical, petrochemical and metallurgical industries. Special dsigns are available to handle aggressive gases. Blolwers used in both conventional and nuclear power plants comply with the various categories of safety regulations.
