Air Recirculator EMS 30

Euroemme Fans:
Air Recirculator EMS 30

Normally
sold with front and back screen but
not louvers. Air recirculator fans used in many industries.

EMS30 Munters/Euroemme FansEMS30 is the ideal air recirculation fan whenever high air movement capacity is required. The unique propeller design is self-cleaning and allows the highest efficiency to be reached.

The square fan housing and air conveyor (venturi) arc made of a strong galvanised sheet-steel. The 6-blade propeller is statically and dynamic balanced for low noise and low vibration. The propeller is available in stainless steel, galvanised steel and pre-coated and galvanised steel.

To improve aerodynamic efficiency, the fan has been developed in Munters euroemme’s R&D lab. The test chamber has been built according to ANSI / AMCA 210-135 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.

Propeller

The propeller is attached to a large v-belt pulley in which is embedded a double ball bearing protected against water. The belt transmission ensures low propeller rpm, which ensures high efficiency, low energy consumption as well as low noise.

Equipment

  • Fan housing and venturi made of strong galvanised sheet-steel.
  • Each motor is individually tested for IN” % quality
    control.
  • Central hub and v-belt pulley are made from die-cast aluminium.
  • Propeller is statically and dynamically balanced.
  • Special threaded bushes on fan’s side panels permit the
    fan to be easily hung.
  • Every fan is individually checked for quality.
