HI-Volume Series

  Features

• The Hi-Volume Belt Drive fan unit is specifically designed to ventilate larger buildings, by moving substantial amounts of air at low pressure with minimal energy consumption.
• Available in two sizes, 1000mm and 1250mm diameter, each with three phase motors and the option of louvres and guards.

  Construction

• Constructed from galvanised steel with a specially designed stainless-steel propeller, these fans are extremely hard wearing and robust in application.
• The drive mechanism comprises of a sealed for life maintenance free ball bearings, which means low noise and vibration levels.
• Units are supplied fully assembled complete with a standard safety guard on suction side and counter balanced air operated louvre shutter on outlet.

  Motors

• The motors are to be foot mounted totally enclosed metric type to IP55, with sealed for life bearings and class F insulation, suitable for operating temperatures up to 50^oC.
• Motors are constructed with a finned aluminium casing to provide excellent heat dissipation resulting in a flexible and durable motor.

  Impellers

• Propeller blades are fixed pitch. The six blades are attached to a mild steel powder coated hub. The complete assembled propeller unit is balanced to grade G6.3.

  Special Features

• A crossed steel framework with the fan hub positioned centrally.
• Fan blades and pulley are located on opposite sides, improving load balancing, thereby increasing bearing and fan life.
• The belt is from reinforced rubber which is easily replaced locally.
• Belt tensioning can be undertaken without removing the guards by using two bolts on the fan casing.
• Easy access to the motor for servicing and maintenance.
• The propeller compromises six self-cleaning blades.
• The aerodynamic blade design ensures volume displacement at low blade pressure.
• Fan housing is manufactured from galvanised sheet steel, corrosion resistant for durability and longevity.
• The heavy-duty construction of the louvres prevents the overlapping slats from vibrating at high air flow.
• When not in operation, heat loss is reduced by the louvres closing automatically.
• Air delivery normally lost due to dirty shutters or to hold shutters open is eliminated.
• The louvres are opened by a centrifugal mechanism, which means that once opened, the louvres do not sap the performance of the fan.
