Central Fans-Colasit Ltd. (CFC) products

The CMV fan range has now been further improved and re-named CMVeco, the casings have been re-designed and as a result the fan efficiencies have increased helping to lower running costs. All units are fitted with an advanced 20 bladed Radial Tipped impeller giving excellent flow characteristics, all impellers within this range (CMVeco125-400) are available from either Injection moulded Fire retardant Polypropylene, Anti-Static Fire Retardant Polypropylene and PVDF, all impellers in this range are balanced to ISO1940/1 – G2.5. Duty ranges from 50m³/hr – 14,000m³/hr with pressures up to 2700Pa and are available either in direct, v-belt or inverter drive versions.

The CMVpro fan range is the latest re-design of the best-in-class CMVeco fan range which has been the market leader for some 60 years. To meet ever growing needs for more efficient fan units Colasit AG have now designed and produced the new CMVpro range fitted with a backward curve impeller, giving efficiencies up to 82%, either with 7 or 11 blades depending upon fan size, all impellers are injection moulded and have streamlined blades to aid efficiency. Materials available are PVDF Fire Retardant Polypropylene, Fire Retardant Anti-Static Polypropylene, the latter being suitable to meet the latest ATEX regulations – BS EN 14986: 2017.

The CMV 450 fan unit is fitted with the same design impeller as the CMVeco range, a 20 bladed Radial Tipped Impeller giving efficiencies of up to 70%, these impellers are CNC machined from Heat Stabilized Polypropylene and balanced to ISO1940/1 – G6.3. Fan casings are also CNC machined either from Black Polypropylene or PVC, GRP reinforcement is available as an extra. Duty ranges from 3000m³/hr – 12,000m³/hr with pressures up to 1900Pa and are available in either direct, v-belt or inverter drive versions.

The CMV500 – CMV1250 fan units are fitted with the same design impeller as the CMVeco range , a 20 bladed Radial Tipped Impeller giving efficiencies of up to 70%, these impellers are CNC machined from Heat Stabilized Polypropylene and balanced to ISO1940/1 – G6.3. Fan casings are also CNC machined either from Black Polypropylene or PVC, GRP reinforcement is available as an extra. As with all our fans the steelworks are galvanised as standard and we only use stainless steel fixings. Duty ranges from 4000m³/hr – 110,000m³/hr with pressures up to 1900Pa and are available in either direct, v-belt or inverter drive versions.

The CMHV fan range was developed in response to our customers’ demands for higher efficiency fans fitted with backward curve impellers to help reduce power consumption and therefore reduce running costs. All units are fitted with an 8 bladed Backward Curve impeller giving efficiencies of up to 80%. The impellers are CNC machined from Heat Stabilized Polypropylene and balanced to ISO1940/1 – G6.3. Fan casings are also CNC machined from Polypropylene or PVC/GRP. Duty ranges from 2000m³/hr – 100,000m³/hr with pressures up to 3000Pa and available in either direct, v-belt or inverter drive versions.

The CPV range of fan units are the most efficient we produce, they are fitted with a 6 bladed Backward Curve impeller giving efficiencies of up to 85%, thus giving appreciable power savings with non-overloading power characteristics.

The BCV range is fitted with a 6 bladed Backward Curve impeller giving efficiencies of up to 80%, these impellers are CNC machined from Heat Stabilized Polypropylene and balanced to ISO1940/1 – G6.3.

The CHVS range of fan units are fitted with a 12 bladed Backward Curve impeller giving efficiencies of up to 80%. These fans are specifically designed to operate in systems with high pressure losses, such as gas scrubbing and Bio Filters, the impellers are CNC machined from Heat Stabilized Polypropylene and balanced to ISO1940/1 – G6.3. Fan casings are also CNC machined either from Black Polypropylene or PVC, GRP reinforcement is available as an extra, as with  all our fans the steelworks are galvanised as standard and we only use stainless steel fixings. Duty ranges from 50m³/hr – 4,200m³/hr with pressures up to 7000Pa and are available in either direct, v -belt or inverter drive versions.

The CHVN range is fitted with a Backward Inclined Impeller giving efficiencies of up to 80%, these impellers are CNC
machined from Heat Stabilized Polypropylene and balanced to ISO1940/1 – G6.3.

CENTRAL FANS – COLASIT LTD also manufactures a range of Plastic Silencers, either splitter type or circular type depending upon the amount of attenuation required for each application. Our circular silencers are available in two types, either straight through or Podded for extra attenuation, the latter having a centrally mounted absorbent pod mounted in the airway to increase its effectiveness, these are available up to 5D (5 x times Dia) and can be supplied either with spigot or flanged ends. Our splitter type silencers are available in standard lengths from 900mm to 2400mm in increments of 300mm, these are flanged both ends as standard. All our silencers are available manufactured from Black Polypropylene (standard), Grey Polypropylene, Grey Fire-retardant Polypropylene and PVC, GRP reinforcement can be also be supplied if required as an extra.
