ABSTRACT:
In the apparatus for regeneration of filters for antidust respirators according to the invention, a pump for blowing air through the filter comprises two coaxially mounted bellows with common bottom and top walls. The bottom wall is rigidly fixed in the casing of the apparatus and has passages for the admission of air into the space between the bellows, and for discharging dust-laden air from the interior of the inner bellows. The top wall supports an adaptor with a cover, for mounting the filter being regenerated.
The apparatus according to the invention enables the bidirectional blowing of the filter, thus improving the quality of regeneration and reducing the time required for cleaning.
