PARAG has specially developed 1200mm, 1400mm & 1600mm diameter Axial Flow FRP Fan Systems comprising of FRP impellers, inlet bell shape, inlet & outlet noise spinners and velocity recovery cone for humidification application under a joint R & D Project with ‘ATIRA’ (Ahmedabad Textile Industry Research Association) & DSIR (Department of Scientific & Industrial Research, Govt. of India). The fan systems have provided unparalleled power saving up to 35% over different makes of Aluminum Fans.
 
The Axial flow fan system essentially consists of following components

Impeller

Outlet Nose Spinner

Casing

Inlet Bell

Inlet Nose Spinner

Outlet Cone

   
Impellers
PARAG impellers of the fan are tested for simulated aerodynamic loads, load deflection characteristics and the strain at the shank.
 
Hub
The design of PARAG fan impeller and hub is based on the worst possible aerodynamic load and centrifugal load scenario. The hub assemblies are statically and dynamically balanced as per ISO standards, to ensure vibration free operations.
 
Pitch Adjustment
PARAG blades of axial-flow fans are often attached to the hubs by a system, which allows the pitch angle to be set at any desired value on assembly. This adjustment pitch feature enables the fan to be supplied preset for exactly the volume flow required, eliminating the waste of power.
 
Casing
The casing encloses the impeller and motor/driving assembly completely. PARAG axial flow fan casings are rolled and flanged from heavy-gauge mild steel.
 
Accessories
Nose Spinner, Outlet Nose Spinner, Inlet Bell Mouth, Outlet Cones are the other important components of the PARAG Fan system and provide higher effciency of opreation, resulting in substaintial energy saving.
