AQUA Ventilated Floor Access

Surespan’s ‘Aqua’ stainless steel  Ventilated Floor Access are rated 250 kg/m2 loading. The cover has a ventilated lid fitted with insect-proof micromesh inserts that allow the hatch to breathe and to prevent it with contamination.

A highly effective EPDM sponge seal is fitted as standard. The stainless steel gas springs ensure the lid is easily opened, which then locks in position with a safety hold-open stay to prevent against accidental closure of the Ventilated Reservoir Covers.

A shrouded padlock hasp is fitted as standard, though other locking options – including locking boxes and electrical interlock – are available.
