Product Guide for Danfoss Airflex Spring Set Drum Type Brakes

Type CTE

BrakeTechnique®, Inc. Products
Static torque capacities up to:
108,350 lb-in
12.200 N-m

Airflex CTE drum style brakes are spring-applied, air released and develops greater torque than Type CS. Its design and construction are ideal for moderate speed, high torque, cyclic applications. The brake is bi-directional, developing approximately the same torque in either direction of drum rotation.


Type CS

BrakeTechnique®, Inc. Products
Static torque capacities up to:
19,800 lb-in
2.235 N-m

Airflex CS drum style brakes are spring-applied and air released. It automatically engages should an air or electrical loss of power occur. The brake is unidirectional, developing less torque in the reverse direction of drum rotation.

Product Guide for Danfoss Airflex Caliper Disc Brakes

Type DP & H

BrakeTechnique®, Inc. Products
Frictional force capacities up to:
5,300 lb-in
23.575 N-m

Airflex caliper design features opposed pistons for balanced braking. Their symmetrical split construction accommodate discs of any thickness and permits mounting from either side or at the split line. Type DP is ideally suited for most stopping and light tensioning applications. An automatic adjustment mechanism compensates for lining wear and maintains constant release clearance and response time. Model H is suited for stopping high inertia loads on large diameter discs. Its design automatically compensates for disc run-out.


Type DPA

BrakeTechnique®, Inc. Products
Frictional force capacities up to:
5,700 lb-in
25.354 N-m

With a symmetrical opposed piston caliper brake design, Danfoss Airflex Type 200DPA brakes offer total stopping power for most high-torque, high-energy applications. The robust design of the 200DPA is engineered for hydraulic actuation and can withstand the tough operating conditions of a wide variety of industrial applications.

Product Guide for Danfoss Airflex Water Cooled Brakes

Type WCS

BrakeTechnique®, Inc. Products
Torque capacities up to:
2,700,000 lb-in
304.830 N-m
Thermal capacities up to:
2,600 HP
1.940 kW

Type WCSB

BrakeTechnique®, Inc. Products
Torque capacities up to:
2,617,000 lb-in
272.510 N-m
Thermal capacities up to:
2,600 HP
1.938 kW

Airflex WCSB is an air applied, water and air cooled multiple disc brake / tensioner designed for heavy-duty brake/tensioning applications. It is similar to the WCB line except for a feature that allows for greater control of the braking/tensioning function.


Type WCB2/WCBD

BrakeTechnique®, Inc. Products
Torque capacities up to:
2,700,000 lb-in
304.830 N-m
Thermal capacities up to:
2,600 HP
1.940 kW

Airflex WC air applied and spring applied water cooled brakes are designed for applications requiring high horsepower absorption. Its design incorporates copper alloy wear plates which transfer heat rapidly to circulating water. They are used for heavy-duty braking and tensioning applications, such as those found in metal and paper processing, as well as for cable tension control on logging, marine mooring and winching equipment. The unit can also be used as an absorption dynamometer.

Product Guide for Danfoss Airflex Rotorseals & Quick Release Valves

Quick Release Valves

BrakeTechnique®, Inc. Products

Airflex Quick Release Valves provide rapid evacuation of pressurized air from pneumatic devices. They provide an exhaust port at the device rather than at the end of a long supply line and/or control component. Exhaust is rapid and positive as soon as there is a pressure drop in the supply line. Mufflers are available to reduce exhaust noise.


Type AA2/B3/C2, Dual Passage, Triple Passage & Internal Rotorseals

BrakeTechnique®, Inc. ProductsBrakeTechnique®, Inc. ProductsBrakeTechnique®, Inc. Products

Airflex rotorseals allow the passage of pressurized fluids from a stationary inlet to a rotating shaft end. Single, dual and triple passage rotorseals are available in a variety of sizes and designs to meet most flow requirements. The multiple passage units can be used for individual control of components mounted on the same shaft, component lubrication and circulating fluid systems. An internal rotorseal is also available.
