The company’s 30,000 sq.ft. manufacturing facility in Noida, near New Delhi, incorporates state of the art equipment and machinery including

(i) high speed punch presses for punching and forming of fan sheet metal components,
(ii) a modern machining center consisting of production lathes, milling machines, drills and slotter to machine turned components such as hubs and shafts,
(iii) automatic impeller assembly machines, spot/mig/tig welding machines, sheet rollers, hydro-pnuematic presses, special purpose jigs/fixtures and
(iv) five computer controlled Dynamic Balancing Machines.

The production process is supported by a full fledged tool room. All tools, jigs and fixtures are designed and developed in house. All fan components are manufactured exclusively with the aid of precision tools, jigs and fixtures. This ensures inbuilt quality and consistency in fan performance fan after fan, year after year.

Consistent with its objectives of designing for optimum quality and performance, the company has its own Aerodynamics Test Laboratory which houses a Mutiple Nozzle Air delivery test chamber as per International Standard AMCA 210 which can test fans of capacity upto 20000 cfm.

To ensure long life and vibration-free operation, each impeller/fan blade is first checked for eccentricity and run- out. Only after passing this quality check, the impeller/fan blade is ready for balancing on computerized dynamic balancing machines. Balancing is done as per balance quality grade G 6.3 of the International Standard ISO 1940.

Our skills, infrastructure and experience are trusted by our customers to optimize performance, minimize costs and increase efficiencies of their products.
