Bronze, tumbled matt finish.Extra low level design with large diameter for ideal air transport.

Simple ontinuous ventilator for above deck mounting, with a cover made from stainless steel and inner section from transparent plastic.Translucent, water-proof, not lockable. 1819-002 without counter flange.

The wind-driven Flettner TCX-2 rotary ventilator draws the stagnant air out of the interior and thus ensures a permanent air exchange and fresh room air. It is suitable for the ventilation of ships and boats and for all types of vehicles, as well as for the permanent ventilation of houses, tiny houses, cabins and containers. The principle of the fan is based on an invention by the German aeronautical engineer Anton Flettner from the 1920s. The manufacturer has redeveloped and optimized the TCX-2 fan. With the help of computer-aided flow models, a high performance fan with many advantages for a wide range of applications has been created:Aerodynamic fan head and base made of white, highly UV-resistant PP plasticShaft and encapsulated bearing made of stainless steel, durable, maintenance-free, very quiet runningVenting capacity approx. 60 cubic meters of air/h at 32 km/h wind speedSimple installation (see also installation videos)Supplied complete with lockable ventilation rosette.For installation on the deck superstructure, wheelhouse roof or vehicle roof, designed for a maximum deck thickness of 10 mm. A circular cut-out with a diameter of 100 mm is required for installation, the inner part and the fan are screwed together with a screw. A pre-glued neoprene rubber seal ensures tightness.For decks and roofs with inner cladding, insulation or double walls, an individually shortenable extension adapter (25 mm to 150 mm) is available, which covers the opening in the inner cladding. A circular cut-out of 186 mm (centered with the deck cut-out) is required in the cladding. The adapter, shortened to the thickness of the inner lining, is inserted from the inside and simply clicked into the counter ring on the inside of the deck. Finally, the ventilation rosette is clicked into the adapter on the outside of the cladding.

This vent, powered only by the wind, is based on an invention by the German airplane pioneer Anton Flettner from the early Twenties.Developed further and optimised by the manufacturer with the aide of computer based flow models, a vent with the highest ventilation capacity possible, came into being. Characteristics: aerodynamic ventilation wheel and body made from UV resistant PP plastic, axle and encapsulated bearing made from stainless steel. Long-lived, maintenance free at very smooth running and little weight. Very simple mounting, the necessary diameter of the roof opening is 100mm. Type TCX-GE: with pipe socket (length 130 mm) for an intake manifold with an inner diameter of 100 mm for the ventilation of remote rooms. Colour: black.These FLETTNER vents are not only suitable for ships or boats, but also for all types of vehicles and stationary ventilation tasks in houses, huts and containers. Suction capacity: approx. 60 m³ air/h at 32 km/h wind speed.

Compact, powerful fan (diameter 150 mm) of the proven "Turbo" series from HELLA.Quiet running quality motor with long service life. The fan housing is made of impact-resistant plastic, the propeller of soft plastic. In front of the guard grille is a two-speed switch for 70 or 95 litres of air output per second.The unit can be mounted upright, suspended or sideways. Can be aligned and locked on all sides. With 1.4 m connection cable. Power consumption 6.5 W.For on-board voltage 12 volts, the black model is also available for 24 volts.

High sided mushroom vent made from strong cast bronze.The high edge stops white water on deck from entering.The convex cover is designed with little overhang in order not to catch loose sheets or lines, when closed.Surface: tumbled matt finish.

This heavy deck vent made of hand-polished cast bronze provides additional light below deck thanks to its glass insert. It can be closed completely watertight from below with a strong toggle screw or from above with a square spindle.

Robust bronze ventilator with polished surface. Closure with strong threaded screw connection. The high rim prevents the ingress of splash water.Depth 10 mm.

High construction made of cast bronze, hand polished. With rubber seal, water-tight.

Lockable deck ventilator in flat design, made of solid cast bronze, hand-polished surface.Manufactured by the traditional British company DAVEY London.Locked with a strong toggle screw.The small version 1454-075 has a spherical cap, the other two sizes have a flatter shape.

Particularly flat mushroom ventilator, turned from solid brass. The fan is attractive due to its dainty dimensions, yet it is very robustly made so that it is tread-proof on deck when closed.

Effective ventilator, made entirely of stainless steel, runs on double ball bearings.Rain-tight through its closed construction.

Aluminium rotating vent, enamelled in dark grey or copper brown.Good throughput despite small dimensions makes it ideal for permanent ventilation onboard or at home.Smooth running, thanks to a vibration-free oil-bath housing,Not intended for combustion gases.Available in two colours: dark grey or copper brown.

Rotating stainless steel vent that can also be used as a gas vent for all opening types, protected against backdrafts and supports the correct draft of the chimney.The (folding) extraction fan runs on ball bearings and is propelled by the wind.The flange is made of a light DURAL-INOX alloy. Available is also a version 240 C with a square ground plate (330 x 330mm) for profiles of 200 x 200mm up to 250 x 250mm. The enclosed attachment bolts allow mounting on pipes of varying diameters.Output data based on 3 beaufort wind velocity (10 kn).

This maintenance-free suction fan, which is powered by the wind according to the Flettner principle, achieves a very high air flow rate. It is rainproof and smooth running. Proven for over 35 years!Construction of aluminum sheet (1 mm thick) with stainless steel axle and two dust-proof, smooth-running ball bearings.The ventilation capacity is specified for a wind speed of 4.5 m/sec.An stick-on flange for flat roofs must be ordered separately.On request, this ventilator is also available with pipe sockets 125 mm or 200 mm.

Automatic vent for aeration and venting using solar power. This vent allows safe, permanent air circulation without tapping into the onboard power system. Integrated solar cells with 1.2 V / 600 m Ah storage battery for day and night use. The vent can be closed manually. Stainless-steel cover, plastic body. Function switch on the inside.

Stainless-steel continuous fan.Under the cover sits a mushroom vent that can be closed from inside to form a watertight seal. With mosquito screen and plastic counterflange for inside.Perfect drainage.
