AIR type protective grilles

Merford AIR type protective grilles combine ventilation and protection for people, animals, equipment and/or machines. The ventilation is usually intended to cool the equipment or to ventilate the room. The grilles are sufficiently impenetrable as far as objects, rain and splashing water are concerned. They therefore offer protection for the items and/or equipment behind them. AIR grilles are available in sendzimir galvanised steel, stainless steel and aluminium.
