100% Clean Warm Air: Only clean, fume-free warm air is blown out of the front of the heater, meaning it is suitable for heating enclosed, poorly ventilated space.

Ducting Connection: Lengths of ducting can be attached to this heater, in order 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.

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.

High Pressure Fan: Capable of pushing warm air over long distances, with an air pressure rating of 250 PA and an airflow rate of 12,800m³/h.

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

Summer-Winter Switch: Allows the high pressure fan to operate without heating, in order to circulate fresh air for ventilation.

Tough & Robust Design: Featuring a strong steel frame with metric bolts, powerful axial fan, digital control of the combustion, fuel pre-heat filter, electronic flame control with photocell, fan-limit thermostat with automatic reset, limit thermostat with manual reset, and two oil filters (oil pump filter and suction filter), this heater is built to perform in challenging areas, including construction sites, workshops, warehouses, agriculture, events and more.

Highly Portable: Crane hooks allow the heater to be lifted on and off transport easily. Large wheels allow the heater to be wheeled into position and re-positioned when required.

Thermostat Connectivity: An optional thermostat can be connected to these heaters, allowing you to set a required temperature within the space. The thermostat will switch the heater on and off as required in order to maintain the set temperature. This saves fuel and adds extra convenience.

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.

Master BV 691 FS Airbus Indirect Space Heater

Part of the efficient AIR-BUS range

The Master BV 691 FS is a large, powerful and highly-efficient 225kW indirect space heater that supplies warm, clean air to any industrial space. Indirect space heaters direct warm air into all intended areas using a ducting system, while any fumes are exhausted separately. The way that these space heaters work means they are safe for heating enclosed areas on construction sites, as well as in warehouses, factories, halls, marquees and event spaces. With an incredible 225kW heat output and 12800m³/h airflow, the BV 691 FS is a cost-effective and reliable climate solution suitable for industrial and commercial applications, including general heating and drying.

Quality Components

With separate Riello burner

The Master BV 691 FS is fitted with a Riello burner. Riello is a reputable brand with a wealth of experience manufacturing high-quality oil burners for industrial, commercial, and domestic applications. The burners are designed to deliver efficiency, the best possible performance, and safe working. The air outlet is interchangeable to allow for connection to 1, 2, or 4 lengths of the robust, flexible ducting. Multiple ducting enables you to vent the warm air into different areas so you can heat separate rooms simultaneously with one space heater, making it an extremely cost-effective investment. All of the internal components, such as the filters, electronic flame control, heater exchanger, suction filter, and the axial fan, are of the highest quality to ensure reliability and long lasting service.

Robust Industrial Space Heater

Durable & resilient

This heavy-duty space heater is constructed with a sturdy steel frame with metric bolts, a stainless steel outer panels, and a stainless steel combustion chamber. The Master BV 691 is designed to withstand the demands of regular use in fast-paced, challenging environments and difficult conditions. The unit is mounted on robust wheels and features four crane hooks for convenient mobility between any location.

Easy To Operate

Straightforward & practical

The digital control of combustion and easy to read display makes the BV 691 FS indirect space heater incredibly simple to operate. Featuring a unique cold-start button for quick operation in harsh environments, there is also a Summer-Winter switch to use the unit for ventilation only. The inclusion of these features makes this an extremely versatile piece of equipment. This model features an air pressure of 250 Pa, however, there is a high pressure version available upon request. The fan-limit thermostat features an automatic reset for further ease of use, and the thermostat also features a manual reset too. As the BV 691 is a large space heater with a considerable out, there is a quick connector for external tanks so you can use whatever size you require to sustain continuous running.
