HIGH PRESSURE BLOWERS HRD Model range without motor This type of high-pressure fan can be driven from an external source via V-belts. The fan housings made of sturdy cast aluminium and the enclosed impellers are manufactured from aluminium sheet. Fans are available with a clockwise or anti-clockwise rotation. A variety of accessories is also available. Special fans for special operating conditions. e.g. increased temperatures of the conveyed medium and ambient temperatures, extended corrosion protection, fan sealing. For more details see HRD catalogue. Model range for frequency converter FU/FUK series devices allow the infinitely variable speed regulation of the induction motors used. The speed can be set from 0 to the max. possible speed typical for the device. No derating is required in the entire speed range. In the case of devices in the FUK series, the frequency converter is connected to the motor. The enclosure is IP54. The max. ambient temperature can range up to 60 degrees Celsius. Devices in the FU series require a separate frequency converter, which is normally accommodated in a switch cabinet. The types 1 T FUK-105/0,9 to 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 protection measures 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. Noise insulating covers These covers are manufactured from sheet steel and covered with a rock wool insulation material, thereby providing 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 side panels can be easily detached and allow easy access to the fan. All the noise insulating covers are designed for fitting to fans with free intake from the atmosphere. Intake Discharge Support for transport Ø 25 Opening for connection cable Disc sound absorbers Are 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. 8 Tube sound absorbers Extremely high-performance sound deadening by means of tubes, which are wound from aluminium foil and have a high tightness as a result of special folding. The inside tube is perforated and insulated with synthetic resinbonded mineral fibre. In addition, the tubes are tightly sealed with aluminium caps. This type of sound absorber can only be mounted with an inlet connection without a flange.

Maintenance-free squirrel cage rotor motors to IP54. The units can only be supplied in the housing position pictured. Accessories: Various connectors for both inlet and outlet side. For more details see FD catalogue. Applications Conveying of plastic granules, plastic waste and light weight bulk materials of all kind provided there is no operational risk RD F range The RD F range can be used for conveying of light and non-abrasive bulk. The blower parts are made of aluminium cast, the impellers are made of welded sheet steel. The solid construction of the practically maintenance free medium pressure blowers is the basis for a long lasting service life and low operation cost. Inspection and cleaning may only be carried out at these blowers by unscrewing the housing cover plate. All drive motors are made to IP 54 enclosure, class F thermal insulation and comply with EN 60034-1 (VDE 530 Part 1). The motor power is oversized in order to have sufficient reserve for the conveying. For more details see RD F catalogue.
