Cone Exhuaust Fans: EC 50

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

EC50 cone fan, a 50' fat equipped with cone discharge, is the ideal fan for high airflow capacity at high static pressures and low energy consumption.

The unique propeller design is self-cleaning and allows the highest efficiency to be reached, while the discharge cone boosts the airflow dramatically:

The square fan housing, cone discharge and air conveyor (venturi) are mode of a strong galvanised sheet-steel. The 3-blade, propeller is statically and dynamic balanced for low noise and low vibration. The propeller is available in stainless steel, galvanised steel and precoated. galvanised steel.

To improve aerodynamic efficiency and reduce pressure losses the cone fan design has been developed in Munters euroemme's R&D lab. The test chamber has been built according to ANSI / AMCA 210-85 Figure 5 specifications. Construction details and airtightress have been verified by personnel of the BESS Lab at the Agricultural Engineering Department, University of Illinois USA.

Propeller, Cone Discharge 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, low energy consumption as well as low anise. 'the cone-discharge is made in I separate pieces to assist with knock-down transportation, and all it galvanised steel.

The shutter is made of galvanised steel for all models. which is stronger than aluminum and plastic. The fan shutter is tightly closed when the fan is not working preventing any air leakage through the fan. The patented centrifugal system prohibits the shutter from being closed by air pressure, keeping the efficiency of the Ian at a peak at all times by keeping the shatter fully and firmly opened. The shutter does not have to be cleaned regularly as dust does not affect its opening and closing movement. All the plastic parts are made of acetalic plastic with UV, protection.

Equipment

• Fan housing, cone and venturi made of strong galvanised sheet-steel
• Shutters are made of pressed galvanised steel in order to assure highest strength
• Each motor is individually tested for 100% quality control
• Central hub and v-belt pulley are made from diecast aluminium
• Optional belt-tensioner available for increased v-belt life and reduced maintenance
• 3-blade propeller is statically and dynamically balanced
• Shutter bearings are maintenance free
• Patented centrifugal system permits a fully and firm opening of the shutter
• Shutter is opened by rotating weights placed over centrifugal system arms
• Shutter opening is not affected by the weight of dust deposited on shutter blades
• A powerful couple of springs keep the shutters firmly closed when the fan is not operating
• Every fan is individually checked for quality
