Industrial Dampers

Industrial Dampers are built to last in harsh environments and perform over a wide range of design conditions. At Nailor Industries, we are offering a variety of high quality products to fit your special needs. Industrial Dampers can be manufactures with rectangular, round or oval frames of heavy gauge steel or stainless steel. Damper models offered as a standard are for isolation, volume control, Backdraft and pressure relief of industrial ventilation ducts and process equipment.
Nailor can provide factory mounted and tested electric, pneumatic or manual actuators to precisely control flow. Nailor can also provide the design experience to modify dampers for custom applications like extreme high or low temperature, corrosive environments or special control requirements. When you are specifying or selecting air control products, Nailor Industries can provide the right Industrial Damper to fit your application and meet your delivery schedule.

Industrial Dampers Includes:

Heavy Duty Industrial Control Dampers • Models: 1970 and 1980 8" x 2" x 12 ga. (203 x 51 x 2.8) coated steel channel • Models: 1975 and 1985 8" x 2" x 10 ga. (203 x 51 x 3.5) coated steel channel. The Nailor Model Series 1970/1980 is an extra heavy duty/industrial control damper designed for use in high pressure industrial HVAC or process air systems. Features include a heavy-duty airfoil blade design that offers precise airflow control or shut-off in applications involving pressure differentials of up to 34" w.g. and velocities up to 6000 fpm, depending on damper width. Models 1975/1985 feature an ultra heavy-duty 10 ga. frame and 2 x12 ga. blades and are suitable for applications of up to 44" w.g. and velocities up to 6000 fpm, depending on damper width.The heavy duty flanged frame, with optional bolt holes, connects easily to flanged duct for fast, secure installation. Model Series1970/1980 may be used for two-position or modulating control utilizing a selection of electric or pneumatic actuators, or can be operated manually with the optional locking hand quadrant.

Heavy Duty Industrial Backdraft Damper
• Model 1900CB 8" x 2" x 14 ga. (203 x 51 x 2) coated steel channel.
Model 1900CB is a heavy duty industrial counterbalanced backdraft damper designed to prevent the backflow of air while allowing for automatic air intake or exhaust in industrial HVAC or process air systems. Features include a rugged vee-blade design, heavy duty blade linkage and ball bearings, that provide smooth, rattle-free operation at velocities of up to 3000 fpm. The counterweight is easily adjusted for desired opening pressure and the heavy duty flanged frame, with optional bolt holes, connects easily to flanged duct for fast, secure installation. Durable steel construction and a wide selection of options make Model 1900CB a versatile, solid performer.

Heavy Duty Industrial Control Damper
• Model 1990
The Nailor Model 1990 is a heavy duty, butterfly type damper designed for use in medium pressure industrial HVAC or process air systems. The model offers precise airflow control or shut-off in applications involving 6" w.g. or higher pressure differentials and velocities up to 6000 fpm, depending on unit size. The heavy duty flanged frame, with optional bolt holes, connects easily to flanged duct for fast, secure installation. Model 1990 may be used for two-position or modulating control utilizing a variety of electric or pneumatic actuators, or can be operated manually with the optional locking hand quadrant.

Heavy Duty Industrial Backdraft Damper
• Model 1905CB 8" x 2" x 10 ga. (203 x 51 x 3.5) coated steel channel.
Model 1905CB is an extra heavy duty industrial counterbalanced backdraft damper designed to prevent the backflow of air while allowing for automatic air intake or exhaust in industrial HVAC or process air systems. Featuring an airfoil blade design, heavy duty blade linkage and ball bearings, Model 1905CB provides smooth, rattle-free operation at velocities of up to 4000 fpm. The counterweight is easily adjusted for desired opening pressure and the extra heavy duty flanged frame, with optional bolt holes, connects easily to flanged duct for fast, secure installation. Rugged steel construction and a wide selection of options make Model 1905CB a versatile performer for the most demanding applications.
