OUTLET DAMPER


(Opposed bladed or parallel bladed types) is best suited for control over board range of air volume and are highly efficient in performance. These dampers can be operated manually or automatic



VARIABLE INLET VANE DAMPER

Designed for accurate control of air volume. The damper will spin the air in the direction of wheel rotation resulting in a maximum saving in power at the reduced ratings desired.



COMMON BASE FRAME

It is structural steel bases with channels which provides common support to fan, motor and drive including guards.



ACCESS DOOR


Access door is provided on the fan casing for inspection and maintenance. Asbestos rope or rubber gasket is used in between fan casing and access door to prevent air leakage. Bolted and quick clamp doors are available.



HEAT SLINGER / SHAFT COOLER AND SHAFT SEAL

Aluminium shaft cooler is used dissipating heat and protecting bearing from high temperature. Shaft cooler is used generally in fans which handle very high temperature flue gas.



HOUSING DRAIN

A socket welded at the lowest point of housing scroll for drainage of water in order to protect the fan from rusting.



INLET AND OUTLET SAFETY SCREENS

Inlet and Outlet Guard are used for protection of the inlet and the outlet from foreign particles entering the fan. It safe guards the inside of the fan from any outside material to enter through the vents.



VIBRATION ISOLATOR

Rubber – in – shear or spring type vibration isolators are available for all sizes and arrangement.



BELT GUARD


A belt guard protects personnel from the moving drive parts. Both standard and totally enclosed type guards are available.



V-BELT DRIVE SET



Drive Set consists of dynamically balanced pulleys and V-Belt. Pulley is made from cast iron or cast sheet material.



COUPLING

Metal Grid type coupling are used where transmission of high power is required. Tyre type couplings are best for low power transmission; they are also flexible in case of out of alignment



FLEXIBLE CONNECTION

Plastic impregnated canvas material is generally used for flexible canvas connection where two metal flanges are fitted at both ends. Flexible material such fire proof cloth, rubberised tarpaulin, neoprene rubber for elevated temperature.
