Schneider Electric Grey Steel Vent Grille, Square Face Slat 130 mm, 160 mm, 0 mm

To get air moving along the right track, install this vent grille from Schneider Electric. It allows air to pass through your vents while controlling the direction and distribution of the flow to stop sensitive equipment from overheating. The unit's made from durable steel, which withstands impact and abrasion in tough settings. Its epoxy-polyester powder finish makes it highly resistant to corrosion and chemicals. You can secure this screen to a wall by inserting screws through the predrilled holes, so installation's a breeze.

• IP23 rating means the grille protects vents from debris and water spray coming from less than 60° vertical

• HVAC systems

The unit's screw holes are 140mm apart. This lets you attach the grille outside the cut-out, so there's no need to make additional adjustments to your wall or ceiling.
