Air Recirculator EMS 50

Euroemme Fans:
Air Recirculator EMS 50

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

EMS50 is the ideal air recirculation fan whenever extra 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) are made of a strong galvanized sheet-steel. The 6-blade propeller is statically and dynamic balanced for low noise and low vibration. The propeller is available in stainless steel, galvanized steel and pre-coated and galvanized 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 210-85 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.

Propeller and shutter

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 and low energy consumption as well as low noise.

Equipment

  • Fan housing and venturi made of strong galvanized sheet-steel.
  • Each motor is individually tested for 100% quality control.
  • Central hub and v-belt pulley are made from die-cast aluminum.
  • Welded wire guards divided into two parts ensure easy maintenance.
  • 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.
