Features of our Positive Displacement Blowers

• Our Positive Displacement Blowers are designed for long running times in continuous operation with high reliability.
• The pressure increase for air and neutral gases is up to 1000 mbar or 800 mbar [200 mbar abs] negative pressure, for volume flows from 19 to 9180 m³/h. The compression is oil free and low pulsation.
• The 3-winged rotors with their shafts are forged from one piece in a die. They also help to reduce the pulsation frequency and the sound level.
• Large ribs on the housing ensure good heat dissipation. The materials used for the GP 30 & GP 35/38 Positive Displacement Blowers are remarkable: Housing, side plates and cover are made of GG20 cast iron. The rotors of the blower types up to GP 35/38 are made of CK45 with a tensile strength of 700 N/mm2. The helical synchronisation wheels made of high-strength case-hardened steel 18CrMo4 are hardened and ground.
• The housings have a pressure shock resistance of 13 bar.
• The blowers are dynamically balanced and tested and documented at the individual assembly stations.
• The selection of bearings is particularly important for longevity and reliability.
• High-quality brand bearings are used depending on the fan size, load and speed. Basis for the determination of the bearings is the design for 60000 operating hours running time, at normal load according to ISO 281.
• The blowers are driven by an electric motor and V-belt drive with automatic belt tension.
• The blowers are mounted on elastic elements, a foundation is not required.
• The on-site commissioning of the blower unit includes installation, pipe connection, oil filling and electrical connection.
• Sound enclosures for indoor and outdoor installation are available as accessories.
• The sound enclosures are designed as segments, lined with insulating material on the inside and powder-coated in RAL 7044/7039 on the outside.
• Each acoustic enclosure is equipped with an electric fan; the instruments can be read from the outside.
