Flue dilution fans

Flue dilution fans are an ideal solution for commercial flue and chimney installations where space is minimal and height is a problem.

They have been specifically designed to handle the exhaust gas products from all types of gas-fired boilers, including fully condensing types.

Flue dilution fans can be set to meet varying load demands (applicable to the relevant plant output) whilst at all times complying with the discharge requirements of 1% CO², as laid down in the Clean Air Act Memorandum and IGE UP/10.

As contractors and installers have come to expect of A1 Flue Systems, our flue dilution fans are manufactured using high-grade stainless steel and are designed to be totally watertight.

The integral invertor allows for fully programmable step sequencing for varying boiler loads. This makes it one of the most energy-efficient flue dilution units available, creating a 60% improvement in energy efficiency.

A typical unit is extremely compact, extending less than one metre into the plant room (assuming a minimum external wall thickness of 150mm). The external 750mm x 750mm combined discharge louvre and air intake extends only 250mm from the outside face of the wall. Where required, this external part of the unit can be powder paint coated to any required RAL colour at a small extra cost.
