Roof fan BLAST / STORM / STORM PRO
Industrial roof fans are devices designed for installation on dedicated roof bases, which effectively remove accumulated hot air from inside buildings, supporting optimal circulation and moisture reduction. They are the foundation of proper ventilation in production halls, large-scale warehouses, public utility facilities, and modern catering vehicles. Our offer includes three series of roof fans adapted to different types of facilities and operational requirements.

Why choose roof fans?
Roof installation frees up space on the façade and internal walls, which is important in facilities with limited external surface area.
Airflow capacity in a wide range from 520 m³/h to 13,800 m³/h allows matching the unit to facilities of different volumes, from workshops to large logistics centres.
The use of modern composites and galvanised steel guarantees resistance to harsh weather and chemical conditions.
The choice between proven AC motors and energy-efficient EC motors allows matching the unit to project priorities.
Motor protection rating IP44 or IP54 (depending on model) ensures protection against dust and moisture.

Which variant to choose?
STORM PRO
Modern design and highest resistance to weather conditions. Lightweight composite casing recommended for large logistics buildings, commercial facilities, and catering vehicles (food trucks).
STORM PRO EC
Modern design in a composite casing and lower operating costs. Energy-efficient EC motor with stepless speed regulation (0–100%) and higher maximum efficiency (up to 13,800 m³/h). Recommended for large logistics and industrial buildings, and demanding catering establishments.
STORM AC
Classic, steel construction at the best price. Traditional AC motor with 1-speed control or via a regulator and efficiency up to 6,700 m³/h. A standard, economic choice for typical small and medium-sized industrial facilities.
STORM EC
Steel construction with an energy-efficient EC motor. Stepless speed regulation (0–100%) and the highest efficiency in the series (up to 13,800 m³/h). For facilities where lower energy consumption and handling large flows are important.
BLAST
Powerful, simple solution for workshops and production halls. Galvanized, powder-coated steel construction with water drainage slots. Available only with an AC motor, recommended for limited investment budgets and simple operation.
What do you gain from our roof fans?
Simple and trouble-free installation — flat and pitched roofs, integration with popular ventilation systems
Installers gain full flexibility. Every roof fan in our range can be installed on both flat and pitched roofs thanks to dedicated roof bases. The STORM and BLAST series design allows seamless integration with leading ventilation systems on the market, significantly reducing project lead times.
Protecting your budget — classic AC for lower investment, EC for lower operating costs
Investing in modern industrial fans guarantees long-term savings. Classic AC models (like STORM and BLAST) offer proven, trouble-free operation and lower upfront costs. EC motor models (available in STORM PRO and STORM series) reduce ongoing electricity bills through smooth speed control.
Weather resistance — materials suited for outdoor installation
Every roof fan is exposed to weather conditions throughout its service life. STORM PRO uses a composite housing resistant to rust and aggressive external environments, while STORM and BLAST use galvanised and powder-coated steel. The BLAST model also features specially designed water drainage slots, extending the service life of the unit.
FAQ
When selecting a unit, you should primarily consider the volume of the facility, the required static pressure, the characteristics of the extracted air and the preferred control method. Industrial roof fans should allow easy integration with the roof base (both flat and pitched roofs). For very demanding external environments, it is worth considering composite housings (as in the STORM PRO series), which are rust-resistant.
Large-volume buildings require high capacity, so the industrial roof fan from the STORM or STORM PRO series works best here. Depending on your needs, this industrial roof fan offers airflows from 450 m³/h to as much as 13,800 m³/h. The use of a composite housing (in PRO models) provides high resistance. The BLAST industrial roof fan works excellently in smaller production halls, with models reaching 2,300 m³/h, 3,700 m³/h and 4,400 m³/h. This number of variants will satisfy every industrial system designer. Every Reventon roof fan is a guarantee of effectiveness.
Our flagship models have a traditional AC motor or an energy-efficient EC motor. Single-phase (230V) or three-phase (400V) power supply allows full matching to the investment.
A roof fan with EC motor enables smooth speed control (0–100%), meaning huge operating cost savings in ventilated spaces. The three-phase motor and high power in roof fans up to 13,800 m³/h guarantee years of stable operation. If technical assistance is needed when selecting industrial equipment, we provide full support. For any questions, contact us.
Although our industrial roof fan and standard roof fan were created for halls and strictly industrial applications, smaller, lower-power models also find use in multi-family residential buildings.
However, it should be remembered that every industrial roof fan generates a certain level of noise (from 52 dB to 85 dB), so quiet operation is a relative feature, dependent on the operating point. Correct temperature and intensive discharge of stale air from the interior are priorities for industrial sectors. Due to their size, pay attention to weight when purchasing, as a roof fan with base can weigh several dozen kilograms.
Every STORM series industrial roof fan has a centrifugal impeller with backward-curved blades, generating higher capacity for demanding extraction processes. We offer a range from 450 m³/h in the STORM 190 AC model, through 880 m³/h in the smallest STORM 225 EC variant, up to an impressive 13,800 m³/h in the largest units, with optimal use of motor power. Housing diameter and connection diameter depend on product dimensions and matched base. See the technical documentation for specificretne wymiary.
Correct installation on a dedicated roof base ensures safe operation of entire industrial ventilation systems. This industrial roof fan can be successfully used in garages, halls and technical rooms, efficiently extracting stale air from the interior. If installation is planned in aggressive livestock facilities, we recommend prior consultation.
