Clean Warm Air

The Master BV 400 produces 100% clean, fume-free warm air. Air is drawn in from the rear, heated through a robust exchanger, and delivered out the front. Combustion by-products remain contained and are safely expelled through the flue system.

Flexible Ducting Options

This heater allows ducting connections to channel heat exactly where you need it. Standard units include one outlet, but a dual outlet adaptor is available. With ducting runs of up to 50m, you can effectively heat separate spaces simultaneously.

Safe & Reliable Operation

A high-pressure fan delivers 6200m³/h airflow with an impressive 500Pa rating, pushing warm air across long distances. A summer-winter switch provides simple fan-only ventilation when heating is not required. The optional thermostat connectivity ensures fuel savings and easy temperature control.

Heavy-Duty Industrial Design

Built for demanding environments, the BV 400 features a stainless steel combustion chamber and strong rotomoulded fuel tank. Its IP44 rating provides resistance to water and dust ingress, making it reliable in tough conditions. Large wheels and a crane hook make transport and positioning easy.

Versatile Heating Power

Equipped with a two-stage Master burner, you can select between 80kW or 110kW outputs. This flexibility helps match heating levels to different environments, maximising fuel efficiency and adaptability for various industrial, event, or construction settings.
