Fast Access ISO-K 250 Blind Door Without Window , Demountable, 3/8 in. Stainless Steel

This Ideal Vacuum Fast Access ISO-K 250 Blind Door (no window) can be mounted to any vacuum chamber with an ISO 250 port (either ISO-K or ISO-F). Blind FADs include a manual knob for closure and are made of stainless steel with a Viton O-ring seal. The approximate pass through diameter of the door opening is 9.6" with an area of 72.4 in². The simple construction makes the door field serviceable. Bakeout to 150°C is permissable. Fast Access ISO Doors are RATED FOR VACUUM ONLY for pressures to 1 x 10^-7 Torr.

Blind FADs are available in ISO-100, 160, 200 and 250 flange sizes. They are used in place of blank ISO-K or ISO-F flanges and allow a user to quickly access the chamber for exchanging test objects. They are often used for load-lock applications. A FAD can be added to a vacuum chamber ISO port at any time.

ISO-K flanged FADs use either single or double claw clamps along with a centering ring fitted with an O-ring for mounting. Use double claw clamps to mount to other ISO-K flanges. Use single claw clamps to mount to ISO-F flanges with bolt holes (smooth bored or threaded). See the table below for claw clamps and centering rings.
