Air curtains
IndustrialAir curtains are devices that create an invisible barrier above doors and gates, which in winter keeps heat inside the building, and in summer blocks the inflow of hot air, dust and insects. Effective separation of climate zones reduces heating and air conditioning costs and protects the indoor microclimate. Our range includes the HUMMER industrial air curtain series, designed for industrial gates in various types of facilities. We also offer device customisation for individual orders.

Why invest in an air curtain?
Effective thermal protection at the entrance — a barrier between indoor and outdoor air
An air curtain creates a sealed barrier above open doors and gates, limiting the mixing of indoor and outdoor air. This is crucial for buildings with high footfall (shops, hotels, offices) and for facilities where warehouse gates remain open during logistics operations.
Reduced heating and air conditioning costs — less heat loss in winter and cooling loss in summer
Reducing air exchange between zones translates directly into lower costs of maintaining the indoor microclimate. In facilities with industrial gates or frequently opened entrance doors, an air curtain can significantly reduce the load on heating systems in winter and air conditioning systems in summer.
Protecting the indoor microclimate — defence against dust, insects and contaminants
The air barrier stops not only excess heat or cold, but also dust, insects and contaminants from the outside air. This is particularly important in catering and food-industry facilities and in rooms with increased hygiene requirements.
Match the heat source
Regardless of the series you choose, you can select the technology to match the installation available at your facility. Each air curtain is available in three variants.
With a water heat exchanger
Uses hot water from the central heating system. Provides high output and the lowest operating costs when heating large volumes. Recommended for facilities equipped with a central heating installation of sufficient capacity.
With an electric heater
A solution for buildings without access to a water installation. The use of modern PTC heaters guarantees fast heating and safe operation. Available with 230 V or 400 V supply depending on power.
Without an exchanger (unheated)
Generate only a strong air stream. Ideal for cold stores and facilities that require separation of climate zones and protection against insects without raising the temperature at the entrance.
Technical parameters
Choosing the right air curtain usually comes down to two factors: the size of the opening and the conditions at the facility.

The HUMMER series is designed for industrial applications and works perfectly in the tall gates of warehouses, production halls, workshops or garages. For small commercial and public-use facilities, such as entrances to supermarkets, shops, hotels and offices, the HUMMER air curtain may be too powerful, and commercial air curtain models should be considered instead.
The maximum installation height for air curtains must not exceed their effective reach. HUMMER curtains are designed for much taller gates and offer an effective reach from 6.5 metres up to as much as 8.0 metres, depending on the model chosen (the HUMMER 200C-EC achieves the greatest air reach (8 m)).
The HUMMER series can be connected to a building management system (BMS). The HMI CURTAIN BMS and HMI EC BMS controllers enable BMS integration. Communication uses the MODBUS protocol (RS485 standard).
Yes, the HUMMER air curtain performs excellently in such conditions. The fan motors in HUMMER curtains have an IP54 rating, meaning their housing protects against dust and against water splashing from any direction. It is worth noting, however, that no air curtain should operate in an environment with extreme dust concentration exceeding 0.3 g/m³.
The series offers three variants that can be flexibly matched to the power supply available at the facility:
Cold / without an exchanger:Curtains without a heat exchanger, marked with the letter "C".
Electric:Curtains with electric heaters, marked with the letter "E".
Water:Curtains with a water heat exchanger connected to the central heating system, marked with the letter "W"
The electric air curtains are equipped with modern, energy-efficient PTC heaters, though they differ in power. The industrial HUMMER models have higher-power heaters, which effectively protect gates up to 8 metres wide, and feature industrial axial fans.
When NOT to choose the industrial HUMMER series:
HUMMER air curtains are not suitable for offices, hotels, small shops and other commercial entrances with a standard height of up to 3 metres. The noise of the industrial motors may cause discomfort for users.
HUMMER air curtains are not suitable for explosion-hazard zones or areas with extreme dust levels: despite their tighter housing (IP54 class), HUMMER curtains do not have ATEX certification. They cannot operate in explosive atmospheres, environments with aggressive chemical fumes, or conditions where dust concentration exceeds 0.3 g/m³.
