8 best roof fans

A device for forcibly evacuating air mass saturated with harmful gases and smoke. Mounted on the roof. It is connected to the interior directly or through ventilation ducts. The principle of operation is axial or centrifugal. Operating mode - exhaust. The main components: the electric motor used as a power drive, housing, impeller. The latter is made of high-quality alloy steel that can withstand a higher temperature of tens of degrees. Selection options: power, speed, performance, noise and installation complexity.

Vents VOK1 200 (VENTS) - from inexpensive

Axial type roof fan with horizontal discharge of polluted air. The drive is from an asynchronous single-phase electric motor with an external rotor. Equipped with temperature protection with the ability to automatically restart.

The body of the aerodynamic device is made of steel with an additional polymer coating. The design is designed for removal of flue gases from the premises of a small internal volume - private houses, farm buildings, workshops, garages.

Pros:

• The ability to adjust the speed of rotation and performance.
• Simple design, easy installation.
• Weather protection.

Minuses:

• Low-power, pulls directly from the room. One meter ventilation channel immediately affects the performance.

VKV-K 125 E Vanvent (VANVENT) - centrifugal type

The design is designed to implement forced ventilation of the premises in order to remove harmful gaseous and suspended solid mineral components (smoke). Mounted directly on the roof. The power drive is a bipolar 220 volt motor.

The possibility of changing the frequency of turns. The product belongs to the centrifugal type, which allowed to reduce the overall dimensions without losing performance. Roof fan fully complies with current regulations, certified.

Pros:

• Compact size, good performance.
• Certification, corrosion protection of components and enclosures.
• Work from the single-phase power supply network.

Minuses:

• Build quality floats slightly, impeller rattles.

SALDA VSA 190 S 3.0 - backward curved blades

The device for removal of gas mixture, burdened with solid inclusions or harmful gases. Equipped with an impeller with backward curved blades to give the air a horizontal direction.

The power drive is an asynchronous motor with the ability to change the speed in the range of 0 ~ 100% of the nominal. Used electronic control or electromechanical, through a transformer. The motor is equipped with thermal protection. Reverse restart function is provided.

Pros:

• Horizontal airflow.
• Power supply from the single-phase power supply network.
• Easy installation and connection.

Minuses:

• The transformer for adjustment costs like the fan itself.

WIND-ABS 160/300 Ballu Machine - performance and low power

A compact, lightweight rooftop fan that combines energy efficiency with acceptable performance. The combination of high-quality plastic and galvanized steel made it possible to achieve an effective removal of air mass from the smoke-filled room.

The installation of an additional ventilation duct allows the unit to be used as a smoke exhaust from the fireplace (briefly) and to increase thrust. The device is designed to work outdoors, taking into account the harmful effects of precipitation and solar radiation.

Pros:

• Quality, performance, small size.
• The combination of plastic and steel.
• Adjustment of turns.

Minuses:

• Confused and contradictory description of installation in the manual, horizontally, vertically, indoors?

Dospel WD 200 - Industrial Applications

Roof fan centrifugal action. Designed for ventilation and selection of air masses from industrial and civil premises. Mounted on warehouse hangars and sports purposes. Used for pumping large volumes of air.

A horizontal flow diversion was applied in order not to fall back into the building. The use of quality materials for the hull and the impeller contributes to increased lifespan.

The use of rolling ball bearings allows the mechanism to operate in continuous mode for tens and hundreds of hours.

Pros:

• Performance, power.
• Weatherproof performance.
• Work from a single-phase network.

Minuses:

• The increased weight, preparation of the basis at a soft roof.

MIXVENT-TH 800 Soler & Palau - 2 speed fan

Supply and exhaust roof fan, equipped with a two-speed engine. The latter is equipped with an effective thermal protection system. The power unit refers to the self-return type.

A constructive possibility of 180 ° rotation of the prefabricated structure for operation as an inlet device is provided. Black polyester paint is applied to create a weatherproof coating. Increased upper threshold of temperature range.

Pros:

• The ability to choose one of two speeds for specific performance.
• Work in exhaust or inlet mode.
• Performance, high speed electric motor.

Minuses:

• At the upper limit, the noise from the air emitted is greatly increased.

Lissant VKM-2,25-2E - vertical air vent

High-performance roof mounted ventilation unit. Designed to divert air and gases from industrial, residential and civil buildings.

Emission is carried out in the vertical direction. Provides remote adjustment of the speed of rotation through the electronic unit. A three-phase electric motor is used.

Pros:

• Performance, power.
• Adjustment of revolutions.
• Weatherproof zinc coating.

Minuses:

• Very noisy, so you can’t stay on the roof for long.

RMVD 500 / 670-4 vim Shuft - power, performance

Industrial grade roof fan with high performance. Able to upgrade to 8400 cubic meters of air in one hour of operation. The change in speed is made by a five-step regulating transformer.

The design is made in weatherproof performance. Effective cooling is carried out using a three-phase electric motor with an external rotor.

Pros:

• High performance, speed selection.
• Galvanized coating.
• Thermal protection.

Minuses:

• Heavy, noisy.
