Ideal for venting the moist warm air from 2-hose air conditioning units. The exhaust hoses are installed in 99% of all cases at an open window."Without an intelligent window installation, such a solution operates extremely inefficiently, as warm outside air continuously flows back in through the window opening, partially negating the cooling performance of the air conditioning unit. In other words: Your mobile air conditioner must not only cool the warm indoor air but also the incoming outside air. This clever sealing fabric significantly increases energy efficiency." This practical helper can be attached to any type of window with just a few simple steps and reliably prevents the backflow of warm outside air into the air-conditioned interior, as well as the intrusion of insects. When installed correctly, the window can be closed as usual without having to remove the fabric. The translucent fabric is made from a durable and water-repellent material with low thermal conductivity. This increases cooling efficiency and reduces consumption costs. The acquisition costs have already paid off in a very short time.  Easy construction  The sealing cloth is attached using the included Velcro tape, which can be removed at any time, similar to mosquito nets. Cleaning in the washing machine is also easily possible.  Suitable for air conditioning units with dual hose technology Air conditioning units with dual hose technology operate with two separate air paths. Commercially available window seals usually only have a zipper opening and are therefore not suitable for use with dual hose devices. This "Airlock" has two openings, allowing for the variable attachment of one "or" two exhaust hoses. If only one opening is needed, the zipper closes the second one invisibly and airtight.  Maximum circulation 400 cm The sum of the three open sides must not exceed 400 cm for this model. If you need a longer cloth, please also consider the model "Airlock1000".  Advantages at a Glance • Increases cooling performance, reduces energy consumption• Suitable for casement windows, tilt windows, and roof windows (must open on one side, do not rotate over the axis) • For air conditioning units with single hose and dual hose technology• Prevents the intrusion of warm air and insects• The window can be closed despite the window sealing.• Amortizes in no time at all• Easy self-assembly  Trotec Article No. 6.100.002.002

This extendable rail simplifies the attachment of the exhaust hose to windows with roller shutters and increases the cooling efficiency of mobile air conditioners. It is easily braced into the guide rails on the left and right and can be precisely extended in width up to a maximum of 136cm. The window cover visually harmonizes perfectly with white windows, allowing for an almost invisible discharge of warm air through the window from the outside. The exhaust hose must have a diameter of Ø15 cm; thinner or thicker hoses do not fit this system. The connection nozzle can be placed in either the left or right area.    Advantages at a Glance   • Particularly simple and visually appealing attachment of the exhaust hose to the window• The cooling efficiency of the air conditioning is increased, as less warm air from outside enters the room.• Uncomplicated installation without craftsmen• Stop hanging exhaust hoses out of the windows• Adjustable variable for window widths of approx. 47 to 136 cm     "The following models from our range are compatible:" • Argo: Argo Chronos • Trotec: PAC Series PAC 2100 X, PAC 2600 X, PAC 3000 X A+, PAC 3500 SH, PAC 3900 X     "For casement windows and casement doors as well as tilt windows and tilt doors, please consider our 'HotAirStopper' as a suitable solution." Trotec Article No. 6.100.000.039
