The design of the Link Vent Mk 2 benefits from aerodynamic features which direct the air flow efficiently through the vents pathway - the canopy extends only 25mm. It has been developed to meet the minimum requirements of the building regulation Part F1:2010; the 2500EQA can be fitted into non habitable rooms such as toilet and bathroom windows which are typically narrower.

The 2500EQA can be used to replace both 2000 and most 4000 vents; it is the same size as typical 2000 vents and has the same, if not improved, EQA as many 4000 vents. The 5000EQA can be used to replace 2 x 4000 vents, meaning fewer vents to fit and rout.

The vent has one of the highest decibel ratings on the market for non-acoustic vents. Improved Db reduces noise to new levels of performance, especially in the closed position. The aesthetically pleasing and patented design helps to reduce the visibility of the trickle vent on a window.

It is available in large range of solid colour or wood grain finishes - internal and external parts can be bought separately for flexible colour choice. The vents are through moulded meaning the colour won’t scratch or peel off. Canopies can be vacuum foiled to match embossed Linear wrapped profiles and the vents can be sprayed to any RAL colour.

The vent has no end caps and is supplied with the fixing clips fitted - you can push fit the vent into place within seconds. The clips automatically centre the vent in the rout, ensuring it is fitted level. If you prefer to screw fix your trickle vents, just pop out the fitted screw caps before fitting and fix as normal.
