Industrial Fan Industries & Applications

Halifax Fan’s bespoke engineered fans meet the demanding needs of pretty much every conceivable centrifugal fan application across the widest possible spectrum of industries worldwide.

INDUCED DRAFT

Where forced draft (FD) fans create positive pressure, induced draft (FD) fans create negative pressure, or put simply, suck air through a system. Frequently ID and FD fans work in concert in boiler applications. In such applications, the ID fans must be constructed to handle high temperature gases and high particulate loadings. ID fans are widely used in the food industry to extract cooking odours from the process before passing them through filters an scrubbers prior to extract to the air.

Relevant construction materials:

  • Stainless Steel

Common fan features

  • Shaft sealing from simple PTFE glands through to nitrogen or water-purged carbon ring seals
  • Acoustic and thermal lagging solutions.
  • Inlet / outlet silencers as well as complete acoustic chambers.
  • Inlet Guide Vane, louvre, butterfly or guillotine dampers.
  • Safety guards and electrical isolators.
  • Ambient air inlet filters and silencers
Applications

Applications involving extreme temperatures, down to -50oC and as high as 850oC, or dealing with explosive, poisonous or corrosive gases, mandate the use of exotic materials such as Hastelloy or Titanium, to ensure long-term reliability and safety.

  • Halifax Fan beat international tariffs by building locally

    Industrial fans are by their very nature, heavy, voluminous and largely made of steel. This means that shipping costs, either to the OEMs, such as oven manufacturers, who will fit them to their machines or to end users like the steel industry, can add enormously to the quoted cost. Additionally, shipping globally can add substantially to the price because of international tariff barriers. Fans shipped into the USA for example, attract a 27% tariff. US built fans avoid this penalty completely.
