Master BV 471FS Air-Bus Jumbo Indirect Heater

100% clean, dry and fume free warm air for places with limited ventilation

The Master BV 471 FS Air-Bus Jumbo Indirect Heater provides large volumes of clean, warm air to large spaces and industrial areas. It is ideal for heating factories, warehouses, construction sites, large halls, marquees and event spaces. The Master BV 471 FS provides 136kW of heating power and a massive airflow of 8500 m³/h. It also has a summer-winter switch, which enables it to be used for ventilation only.

This space heater is constructed with high quality materials and components to ensure efficiency and long lasting service. The steel frame is strong and rigid with metric bolts and robust outer panels, making it incredibly resilient in challenging environments. Both the high efficiency heater exchanger and combustion chamber are stainless steel to offer corrosion resistance and reliable stability. There are two robust wheels at the base of the frame and four strong crane hooks, for portability. The Master BV 471FS Air-Bus heater also features a powerful axial fan, oil filters, and electronic flame control.

With its digital control and display screens, the Master BV 471 FS indirect heater is easy to use. There are automatic and manual reset buttons for fan-limit thermostat and limit thermostat. The air outlet can be connected to various lengths of ducting to direct the warm air into the space effectively. These heaters can also be fitted with 2 way or 4 way warm air outlets for ducting, allowing you to heat more than 1 space at the same time. There is no internal fuel tank, but it does have a quick connector for an external fuel tank. Connection to an optional room thermostat is possible via the thermostat socket.

136kW Max Heating Capacity: The Master BV 471FS Air-Bus Jumbo Indirect Heater can deliver 136kW of heat to warm up large areas quickly and efficiently.

Powerful Axial Fan: This space heater can push clean air over long distances, with an airflow rate of 8500m³/h and an air pressure of 250 Pa.

Supplies Clean Warm Air: The Master BV 471FS provides a large volume of 100% clean, dry and fume free warm air. It is safe and suitable for safe for enclosed, poorly ventilated areas, like marquees, tents, halls, and more.

Flue Gas Exhaust: Combustion by-products are exhausted out of the top of the heater. Sections of flue pipe are available separately, allowing you to safely vent exhaust fumes away from the space.

Summer/Winter Switch: This allows the fan to be used without the heating element, to provide ventilation during warmer months.

Overheat Thermostats With Reset: The limit thermostats shut the heater and the axial fans down automatically if they overheat. The fan-limit thermostat has an automatic restart, and the heater thermostat has a manual restart.

Ducting Connection: Lengths of ducting can be attached to this heater to direct the clean warm air into the space that you need to heat. Optional ducting adaptors are available with 1, 2 or 4 outlets, allowing separate lengths of ducting to be used to direct air to different areas. Ducting makes it possible to heat a range of large and enclosed areas safely and evenly, and heat different rooms at the same time.

Thermostat Connectivity: An optional thermostat can be connected to the heater, allowing you to set a required temperature within the space. The thermostat will switch the heater on and off as required to maintain the set temperature, saving on fuel consumption.

Tough & Robust Heater: The Master BV 471FS is built to perform in challenging areas, including construction sites, workshops, warehouses, agriculture, events and more. It has a stainless steel combustion chamber, a steel frame with metric bolts, and a heat exchanger made from stainless steel pipes.

Unique ‘Cold Start’ Button: Allows the heater to start up reliably even in very cold environments.

Quick Connector To External Tank: This heater features no internal fuel tank. It is designed to be connected to an external fuel tank of your choice, using the quick connector.
