Walk-in blast rooms can accommodate big and extra-big components.
The waffle-floor system requires no mechanical recovery systems such as screw conveyors, bucket elevators etc. which are subject to high wear.
Contrary to conventional blast rooms our waffle-floor blast rooms require no pits or foundations.
Existing rooms can easily be retrofitted with the waffle-floor systems.
Using the air flow from the dust collector the spent abrasive is collected in the waffle floor having a thickness of 220 to 260 mm only, and picked up from there.
The whole base area serves for recovering; air inlet baffles are distributed over the room ceiling.
Due to the vertical downdraught ventilation produced inside the enclosure the dust is immediately trapped. This principle guarantees excellent visibility which is unknown with conventional systems and greatly increases productivity.
