■UsesGeneral●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

■FeaturesHOH 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.

Performance data of fans are measurements obtained based on JIS B 8330: Testing and Inspection Methods for Fans.All the performance curves in this catalog are indicated under standard conditions (air at a temperature of 20°C, an absolute pressure of 101.3kPa, and a relative humidity of 65%). Therefore, for handling gases at temperatures other than 20°C, make a selection according to the pressure obtained by the following calculation formula.

When the suction air temperature drops below 20°C, take 3.5% at 10°C and 7.5% at 0°C with respect to the motor output in the catalog.

P'：Static pressure to be applied to the performance table (static pressure at 20°C) PaP：Static pressure required at t°C Pat ：Suction air temperature °C

※1 OB type is not provided with duct fixing rivet holes. Types other than OB are provided with rivet holes.※2 Supported only for No. 4½ or higher. (No. 10 is vertical split type as a standard.)※3 As for No.1 – 3, gas contact parts are made of SUS. Those made of SS are supported by CLF6-OB model.)※4 Materials of designated parts can be changed. (For example, the impeller alone is made of SUS304; the case is made of SPHC, SS400; and the shaft is made of S45C.)※5 Anti-vibration rubber mount, combination spring anti-vibration rubber mount, and anti-vibration spring mount can be supported. They can also come with earthquake-resistant stopper bolts.※6 Anti-vibration rubber mount, combination spring anti-vibration rubber mount, and anti-vibration spring mount can be supported. They can also come with earthquake-resistant stopper bolts. Anti-vibration rubber hangers and anti-vibration spring hangers can also be supported.※7 Supported only for No. 4½ or lower.※8 Supported only for No. 4 or lower.※9 Motors are in accordance with motor manufacturers’ coating.※10 Epoxy resin coating cannot be installed outdoors. Comparable corrosion resistance required in outdoor installation is supported by coating against salt damage.※11 Impellers are uncoated in principle (in the case of standard coating).※12 Polyester urethane based powder coating 7.5BG5/1.5 is applied to some parts depending on fan number.※13 If the temperature of gas handled exceeds 90°C, heat-resistant silver coating is applied.※14 Parts of stainless steel material are uncoated in principle.※15 Heat-resistant pillow block is used according to temperature classification.※16 Supported only for No. 5 or lower.※17 Welded structure of casing is drained (socket mounted) as a standard.※18 Limited to welded structure of casing.※19 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 CLFⅡ-OB model (No.1 – No.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.※20 Unsupported for No. 2 or lower.※21 Unsupported for No. 1½ or lower.※22 Consideration is required for No. 1 – 1¾ as occasion arises. Supported for No. 2 – 3 within the motor output range in outline drawing.※23 Supported within the motor output range in outline drawing.※24 Common base (A/D).※25 Horizontal split.※26 Base, bearing stand, belt guard, and bearing guard are targeted.※27 Supported only for No. 4 or lower. For No. 4½ or higher, contact us.
