Description

The ST12 SEAT corrosion resistant fan is designed to deliver high airflow, under low to medium pressures in industrial fume extraction. 

 

Key Features:

  • Single piece moulded UV-treated, high density polypropylene housing.
  • Industry standard round spigot sizes.
  • Delivers relatively low airflow, under high system pressures.
  • Multiple motor configurations: including single phase (1~) and three phase (3~).
  • Handings & orientation options: LG0, LG45, LG90, LG225, LG270, LG315, RD0, RD45, RD90, RD135, RD225, RD270, RD315. For LG 180 & RD180 we suggest discussing with our team. 
  • Inverter compatibility: We recommended soft starts and speed control on larger fans.
  • Temperature rated up to 60°C.
  • ATEX certified carbon loaded polypropylene variant for use in Zone 2 hazardous areas available.

Handings & Orientation

 

The correct handings and orientation directly impacts the airflow direction of the fan within the system or to minimise the bends in system design. Incorrect handing or orientation can result in inefficient airflow patterns and poorly captured fumes. Incorrect choices can also affect noise and vibrations levels generated by the fan. You should advise your fan supplier of the required fan handing and orientation at the point of order. A project can be stalled or delayed as fan suppliers will not process an order without this information. This ensures the product performs as required in your system. 

 

ST12 Fan handings

 

Depending on the desired airflow pattern and the specific requirements of the extraction system, the impeller rotation can be set to LG (Right rotation) or RD (Left rotation). Multiple discharge positions are available but it is important to ensure that the right handing is chosen before installation. We do not advise that any contractors change the handing themselves, this can lead to the system only achieving 30% of the duty.

Additional Information

Other sizes include the ST10, ST14, ST16 & ST18 models.

 

For applications requiring a higher airflow performance the S range which provides relatively low to medium pressures may be more suitable. See models S15, S20, S25, S30, S35 & S50.
