Sirocco Fans General Catalog CLF 60Hz

Centrifugal fans CLF model Uses General Ventilation and air-conditioning of buildings, condominiums, hospitals, schools, restaurants, complexes, etc. Air blow/exhaust, and cooling of various devices Boilers and dryers Ventilation of factories, warehouses, car parking garages, and underground malls General air blow/exhaust CLF6-OB model and CLFII-OB model Air exhaust of kitchens and toilets CLFII-OB model (gas contact parts made of SUS304 Exhaust of high-humidity gases Exhaust of gases containing some corrosive gases Features HOH type While being compact, it is high in air volume, and does not require a large installation area as the impeller is attached to the motor shaft. With little vibration, operation is quiet as it is directly driven by the motor. RS type, OB type, and RD type These are high-efficiency types that deliver great performance using low power. Optimum selection can be made appropriately due to many rotation speeds. Installation is easy as they are designed to be as compact as possible. Sufficient performance is delivered at low rotation speed with noise generation reduced.

All the performance curves in this catalog are indicated under standard conditions (air at a temperature of 0 C, an absolute pressure of 0.3kPa, and a relative humidity of 65%). Therefore, for handling gases at temperatures other than 0 C, make a selection according to the pressure obtained by the following calculation formula. Absolute temperature 73 P' P P Absolute temperature 0 93 P'Static pressure to be applied to the performance table (static pressure at 0 C) Pa PStatic pressure required at t C Pa t Suction air temperature C When the suction air temperature drops below 0 C, take 3.5% at 0 C and 7.5% at 0 C with respect to the motor output in the catalog.

Polyester urethane based powder coating 7.5BG5/.5 is applied to some parts depending on fan number. 3 If the temperature of gas handled exceeds 90 C, heat-resistant silver coating is applied. 4 Parts of stainless steel material are uncoated in principle. 5 Heat-resistant pillow block is used according to temperature classification. 6 Supported only for 5 or lower. 7 Welded structure of casing is drained (socket mounted) as a standard. 8 Limited to welded structure of casing. 9 They can also come with a specialized drain cock/valve. However, pay attention to the following for floor type. CLF6-HOH model, CLF6-RS model, CLF5-RS model, CLF6-OB model, and CLF-OB model ( 3) have no space to install a cock/valve because the drain socket is installed at the bottom of the casing. If drain piping is required, make an arrangement for the foundation. 0 Unsupported for or lower. Unsupported for ½ or lower. Consideration is required for ¾ as occasion arises.
