- Description
OS single inlet fans, according to PS 12 3237 are radial transport pressure fans, which are produced in sizes 400, 500, 630, 800 and 1000. They are driven by an electric motor via belt drive, the impeller is mounted overhung on the shaft. To extend the fan power output various ratios with different engine wattages can be selected. Fans are available with either a bare shaft (without transmission and electric motor) or transfer (complete belt drive and motor). The fan with gear coupling can be ordered on a common frame
.
- Use
Fans are used to transport non-sticking industrial waste in the woodworking industry (sawdust, shavings, textile waste ...), paper mills and similar industries. They can only be used for the transfer of V-belts and for the transport of air without danger of explosion. The fans are not gas-tight and should not be used for the transport of harmful and odorous air mass.
- Working conditions
Fans can transport the above industrial waste or clean air at a temperature range of -20 ° C to + 85 ° C. Fans are suitable for air mass transport of industrial waste and can be placed in environments without the danger of explosion (BNV - CSN 33 2320) at an ambient temperature of -20 ° C to +40 ° C. The fan can be operated only under conditions and with parameters that have been approved by the manufacturer or according to the data plate on the fan.
