If the ventilation in your house does not cope with its tasks, has a long length or complex branched moves, only a duct fan will help in its work. Those who are faced with the problem of low air flow in the premises, we offer an overview of the best exhaust devices of different performance. Among them there is certainly a suitable option.

Vents TT Silent-M - the most silent and protected
The family of silent fans is produced in a waterproof case made of steel with polymer powder coating, which prevents its corrosion. The series includes 6 models with a capacity from 240 to 1950 m3 / h.
The special design of the impeller made it possible to obtain greater efficiency of the devices without increasing energy consumption. And the engines themselves were originally designed to work in two speeds.
Pros:
- Really quiet operation at 28 dB.
- Sound and heat insulated mineral water body.
- Sealed terminal box in which the contacts will not oxidize even at high humidity in the mine.
- There is protection against motor overload.
- An opportunity to mount the case with an inclination in relation to an axis of fixture.
Minuses:
- The regulator for external speed control needs to be ordered separately.
Blauberg TURBO - light version
These fans are also designed to work in rooms with high humidity. Only their body is not made of steel, but of durable impact-resistant plastic.
The Turbo family is represented on the market by six models with a capacity of 170-1360 m3 / h. The drive uses a two-speed motor.
Pros:
- The special composition of the applied plastic has an increased resistance to fire.
- Simplified disassembly of the engine block together with the impeller for maintenance - without unwinding the ventilation duct.
- Built-in overheating protection.
- The ability to choose a model for connection to pipes of any diameter from 97 to 247 mm.
Minuses:
- Noise performance increases with increasing fan power. And if the low-end models have a low (27-34 dB), then the older ones reach 55.
DiCiTi Cyclone-EBM - high capacity centrifugal fans
Powerful centrifugal fans of circular cross section for the organization of effective air exchange in large and crowded rooms. This line was the result of the joint work of the Russian company ERA and German specialists from EBM-Papst, engaged in the production of professional ventilation systems.
The range of Cyclone has six models of different diameters with a capacity from 265 to 1700 m3 / h.
Pros:
- Especially strong and tight case from a composite.
- German motors with ultra-precise bearings and a great resource.
- When overheating, a protective shutdown is triggered, but as soon as the engine cools down, the fan will start up again.
- Each impeller is carefully balanced, which made it possible to obtain an acceptable noise level with high fan performance.
- Dust and moisture protection of motors corresponds to the class ip44.
Minuses:
- Despite all the efforts of the developers, the noise level remained quite high, if we compare the Cyclone with axial models (from 52 to 57 dB).
Soler & Palau OZEO-E - multizone devices for branched ventilation systems
Unique in design fans are designed to connect directly to several branches of the mine.
This unit is enough to ensure normal air exchange at the same time in the kitchen, bathroom and a couple more rooms - there are 4 suction inlets, plus one outlet. The range of multizone fans includes 3 models with a capacity of 420 m3 / h.
Pros:
- Three speeds of the engine.
- Extended operating temperature range (-20 .. + 45 ° С).
- Relatively low noise performance of 38 dB.
- Convenient control from the console - wired or with a radio transmitter.
- Included are stubs to close unused connections.
Minuses:
- Price depending on the availability of the console and its design ranges from 11-18 thousand rubles.
MMotors VOK-T with non-return valve - heat-resistant fans
A special type of ducts for hot rooms (saunas and baths) have an additional butterfly valve, which prevents the flow of cold air from outside.
The series of heat-resistant units of the Bulgarian company includes 8 models with a capacity from 150 to 240 m3 / h, which can operate at a temperature of -50 .. + 150 ° C.
Pros:
- Durable and corrosion-resistant aluminum housing.
- The same aluminum or heat-resistant polyamide impeller (material depends on the specific model).
- The possibility of wall and ceiling installation.
- Double insulation to prevent condensation inside the fan.
- A sufficient level of engine dust protection - ip44.
Minuses:
- The fan resource on the bearing is slightly less than that of household models (30 thousand hours against 40).
