Air Blowers: EDC18 - EDC24

USGR offers a wide variety of exhaust fans for many industries,
engineered, designed and priced to meet all climates of the world.

Air blowers are developed to break up stratified heat, humidity and stagy ant air. The unique propeller design is self-cleaning and, together with air flow rectifiers, allows the highest efficiency to be reached.

The round housing and air flow rectifiers are made of a strong galvanised sheet-steel. The 6-blade propeller is statically and dynamic balanced for low noise and low vibration.

TO improve aerodynamic efficiency. the air blower has been developed in Munters euroemme's R&D lab. The test chamber has been built according to ANSI / AMCA 2 10-85 Figure 15 specifications. Construction details and airtightness have been verified by personnel of the BESS Lab at the Agricultural Engineering Department, University- of Illinois - USA.

Equipment

  • Air blower housing is made of strong, pre-coated, galvanised sheet-steel.
  • Each motor is individually tested for 100% quality control.
  • Propeller is statically and dynamically balanced.
  • Special hooks on housing permit the blower to be easily hung.
  • The smooth air recirculation obtained by using air blowers helps to prevent condensation.
  • Air recirculation helps to prevent crops disease and helps crops transpiration.
  • Every blower is individually checked for quality.
