Manufacturer of products from polypropylene

Polypropylene radial fans

Descriptive part:

The main specialization of UralActiv Ltd. (Yekaterinburg) is the manufacturing and supplies of industrial polymer radial fans of acid-resistant type. These fans are manufactured in all standard sizes of low pressure (RVND), of medium pressure (RVSD) and of high pressure (RVVD). Their capacity is 180-100000 m3/h and the pressure up to 8000 Pa for different chemical acid or alkali mediums. The service life is about 50 years in aggressive gas medium. 

Full information on the fan is available in PDF catalog

DESCRIPTION

There is a special model of fan presented – fan for laboratories and for exhaust fume hoods RVND-L-164. This fan is intended for airways with diameter 160 mm. Its capacity is 180-1600 m3/h.

Detailed information about fans you can find in PDF-catalogue.

Questionnaire for fan selection

Brief description

The housing of fans (scroll housing) can be made from:
- polypropylene block copolymer, grey color, RAL7032
- polyethylene, black color.

There also can other types of polymeric material (PVC, PVDF) according to the medium and its concentration.

Running wheels of fans can be made from:
- steel with PVC-coating
- polypropylene
- reinforced chemical-resistant polymer.

Basic specification of PP radial fans:
- Welded and corrugated chemically resistant rubber (consisting from 6 waves);
- vibration absorber;
- Pipe for condensate drain;
- All inside parts of the fan (balancing weight, shaft, hub) have polymeric coating.

Types of acid-resistant fans
- Acid-resistant fans of industrial type
- Acid-resistant fans of explosion-proof type according to the technical specification ТУ 4861-002-95801889-2016.

Operational conditions of polypropylene fans:
Maximal service life of plastic fans is achieved at the operating temperature +5…+60 centigrade (temperature of gases and of place for installation). It is available to install the fan outside and to operate it at the negative temperature. In this case is necessary to protect the fan from the ultraviolet light. In any case the service life will decrease as compared with inside installation.

The catalogue on plastic fans offers standard solutions. In case you need a fan for specific conditions please fill out the questionnaire.

We offer special conditions for the cooperation with the engineering companies from full technical support to the final result.

Also our company designs and manufactures absorption systems for wet gas cleaning – polypropylene vertical and horizontal scrubbers. The use of scrubbers not only increases the corporate culture but also helps to protect the environment and prolongs the service life of fans.

We manufacture all types of ventilation system’s parts from polymers: from straight-line sections to valves, acoustic absorbers and others.

Necessary data to select proper fan:
- Operating point of plastic fan, its capacity and full pressure.
- Gas temperature.
- Temperature of place for fan installation.
- Composition and concentration of the medium (mg/m3 and the formula).
- Does frequency control require?
- Does explosion protection require?
- Does scrubber for air cleaning require?
