Cask Breather

In stock and ready to ship.

Prevent too much air from entering your cask with a Cask Breather from the real ale experts at Harry Mason.


    This Cask Breather from the real ale experts at Harry Mason is an automated version of the hard and soft peg or spile.

    Also called a race ventilator or auto vent, it can add days on to the life span of your ale thanks to the non-return valve (duck bill) which prevents too much air from entering the cask. When the beer is dispensed, the vacuum within the cask forces the valve to open.

    Made from high-impact-resistant, food-grade material, this particular model can be used on either vertical dispense systems or in the traditional lay down method.

    Don't let your cask ale spoil prematurely. Order a Cask Breather by Harry Mason today.

    • Replace Soft and Hard Pegs
    • Increase the life span of the beer

    Works great
    Much easier than using hard and soft spile, only takes in oxygen when needed
