HIGH PRESSURE BLOWERS
Model range without motor This type of high-pressure fan can be driven from anexternal source via V-belts. The fan housings made of sturdy cast aluminium and the enclosed impellers aremanufactured from aluminium sheet. Fans are availablewith a clockwise or anti-clockwise rotation. A variety ofaccessories is also available. Special fans for special ope-rating conditions. e.g. increased temperatures of theconveyed medium and ambient temperatures, extendedcorrosion protection, fan sealing.
Model range for frequency converterFU/FUK series devices allow the infinitely variable speedregulation of the induction motors used. The speed canbe set from 0 to the max. possible speed typical for thedevice. No derating is required in the entire speed range.In the case of devices in the FUK series, the frequencyconverter is connected to the motor. The enclosure isIP54. The max. ambient temperature can range up to 60 degrees Celsius. Devices in the FU series require aseparate frequency converter, which is normally accom-modated in a switch cabinet. The types 1 T FUK-105/0,9to HRD 65 FUK-100/7,5 are deliverable with build up frequency converter.

ELECTROR ORIGINAL ACCESSORIES
High performance noise protection systems.Due to design, all the fans from Elektror have a low noise level in proportion to their output. Extra noise protectionmeasures may be required in individual cases, however, depending on the purpose or also on statutory regulations. For these cases, Elektror offers a number of possibilities for active noise protection.
Disc sound absorbersAre manufactured exclusively from sheet steel in two piece execution. Elektror disc sound absorbers are fitted ex works with an integrated intake screen. Foam plastic is used as an insulation material in the large discs.
Tube sound absorbersExtremely high-performance sound deadening by meansof tubes, which are wound from aluminium foil and havea high tightness as a result of special folding. The insidetube is perforated and insulated with synthetic resin-bonded mineral fibre.
In addition, the tubes are tightly sealed with aluminiumcaps. This type of sound absorber can only be mountedwith an inlet connection without a flange.
Noise insulating coversThese covers are manufactured from sheet steel and cove-red with a rock wool insulation material, thereby provi-ding effective noise protection. The covers are mounted on a U-shaped base plate, which is suitable for screwing
on to a bed (drill holes are present ex works). The sidepanels can be easily detached and allow easy access tothe fan. All the noise insulating covers are designed forfitting to fans with free intake from the atmosphere.

FD/RD F
FD rangeBlower housings made of abrasion resistant cast iron,hinged housing cover lid for inspection and cleaning,welded sheet steel impellers with radial blades.Maintenance-free squirrel cage rotor motors to IP54.The units can only be supplied in the housing positionpictured. Accessories: Various connectors for both inletand outlet side. For more details see FD catalogue.Application:• Conveying of plastic granules, plastic waste and
lightweight bulk materials of all kind provided there is no operational risk.
RD F rangeThe RD F range can be used for conveying of light andnon-abrasive bulk. The blower parts are made of alumi-nium cast, the impellers are made of welded sheet steel.The solid construction of the practically maintenancefree medium pressure blowers is the basis for a longlasting service life and low operation cost. Inspectionand cleaning may only be carried out at these blowersby unscrewing the housing cover plate. All drive motors are made to IP 54 enclosure, class Fthermal insulation and comply with EN 60034-1 (VDE530 Part 1). The motor power is oversized in order tohave sufficient reserve for the conveying.For more details see FD / RD F catalogue.Application:• Conveying of lightweight bulk material of all kind
provided there is no operational risk.
