Abstract (en)
[origin: EP0135251A2] A safety cabinet which is readily serviceable from either front or rear and has smaller front to rear dimensions than hitherto is constructed with air transfer ducts (60) extending up the two sides of the cabinet. Air flows from fans (44a, 44b) downwards through a filter (26) to the working chamber (24). This air, together with air drawn in through opening (36), then flows via an air space below the working surface and via said side ducts (60) back to an air entry compartment (54) at the top of the cabinet for recirculation through the working chamber (24).
