VC 14-46 NZh #2 w/motor AIR 63 A4 0.25 kW 1500 rpm, execution 1

Medium-pressure centrifugal fan of the VC 14-46 NZh #2 w/motor AIR 63 A4 0.25 kW 1500 rpm series for general industrial use, made of AISI 403 stainless steel for aggressive environments.

This fan is designed for ventilation or air conditioning systems and other gas mixtures contaminated with aggressive gases and vapors, where the resistance of stainless steel is higher than that of ordinary steel, and which do not contain fibrous materials, sticky substances, dust, or other solid impurities in an amount not exceeding 100 mg/m³ under moderate (U) climate conditions (placement category 3) and tropical (T) climate (placement category 2) according to DSTU 15150.

This model is an analogue of medium-pressure centrifugal fans VR-287-46.1, VR 320-46, VR-300-46, VR 300-45, VR 289-46, VR 15-45.

The centrifugal fan VC 14-46 NZH #2 (VR-287-46.1) consists of the following units, which can be purchased separately:

Purpose of centrifugal fans VC 14-46 NZh #2 w/motor AIR 63 A4 0.25 kW 1500 rpm (VR-287-46.1):

The VC 14-46 NZh #2 w/motor AIR 63 A4 0.25 kW 1500 rpm centrifugal fan made of stainless steel is intended for moving air and other gas mixtures contaminated with aggressive gases and vapors, where the resistance of stainless steel is higher than that of ordinary steel, not containing sticky substances, fibrous materials, as well as dust and other solid impurities in an amount not exceeding 100 mg/m³.

Centrifugal fans VC 14-46 NZh #2 w/motor AIR 63 A4 0.25 kW 1500 rpm (VR-287-46.1) are used in:

• air conditioning systems
• ventilation systems
• air heating systems
• other sanitary and industrial purposes

The VC 14-46 NZh #2 w/motor AIR 63 A4 0.25 kW 1500 rpm (VR-287-46.1) centrifugal fan operates in moderate climate conditions at ambient temperatures from -40 °C to +40 °C. The temperature of the conveyed medium must not exceed 80 °C.

Operating principle of the centrifugal fan VC 14-46 NZh #2 w/motor AIR 63 A4 0.25 kW 1500 rpm (VR-287-46.1):

Air, by transferring energy from the impeller blades, enters the fan under the influence of centrifugal force at a 90-degree angle and moves in a radial direction into the volute of the spiral casing; in the volute, moving along the spiral-shaped casing, under pressure, it is directed through the fan outlet.

Completeness of the centrifugal fan VC 14-46 NZh #2 w/motor AIR 63 A4 0.25 kW 1500 rpm (VR-287-46.1):

• spiral casing,
• impeller,
• frame,
• collector,
• Electric motor AIR 63 A4

The impeller consists of front and rear discs, 32 sheet blades, and a hub. The fan frame is welded. The base has a hole for installation on vibration isolators or a foundation. The electric motor and cover are mounted on the frame. The conical collector for supplying air to the impeller is fixed to the inlet pipe. The overlap between the collector and the front disc of the impeller is adjusted by axial movement of the collector in the inlet pipe.
