Gas Blowers — selection guide
Gas Blowers: 56 models, maximum airflow 87–260 m³/h, static pressure to 4,100 Pa, across 0 series.
Gas blowers supply combustion air to premix and forced-draft burners: 56 FL-series models from 87 to 260 m³/h at static pressures up to about 4,100 Pa, with 34–300 W motors on 230 / 220 V and 115 V AC, and 12 / 24 V DC versions for modulating control. The model code carries the frame and airflow class — FL085034Y is the 85 mm frame, 34 m³/h class.
The pressure capability is what sets this family apart from ordinary compact blowers: a condensing boiler must push air through the burner, heat exchanger and flue, and the blower curve has to cover the maximum firing rate with margin for heat-exchanger fouling.
How to select from this range
- Select by the burner pressure drop at maximum firing rate plus flue resistance, with margin for ageing of the heat exchanger.
- Modulating burners need DC or EC versions with PWM control and tacho feedback; single-stage burners can use AC.
- Match the outlet flange and venturi interface to the burner; adapter plates are available.
- State the air-inlet temperature and the sealed-combustion requirement of the installation.
Where these fans are used
- Condensing gas boilers
- Gas water heaters
- Premix burners and industrial heaters
Every figure above is measured on our own test rigs per AMCA 210 / ISO 5801 methods — see the test labs and certificates. Final selection is confirmed at the duty point and by project validation.
FAQ — Gas Blowers
What pressure can the gas blowers develop?
Up to about 4,100 Pa static pressure at low airflow; the curve on each model page shows the pressure available at your firing-rate airflow.
Can the blower be modulated with the burner?
DC and EC models accept PWM control and return a tacho signal so the boiler controller can hold the air-to-gas ratio across the modulation range.
Do you match the blower to a specific burner?
Yes. Send the burner model, firing range and flue length; we match blower, flange and control interface and ship samples in 1–3 days.
