<p>PURPOSE:To conduct an efficient deodorization by delivering liquid deodorizer to a spray nozzle with a deodorizer feed pump for spraying a deodorizing filter therewith an making the amount of deodorizer fed by the feed pump adjustable in conjunction with the amount of air blown by an air blower. CONSTITUTION:An air blower 3 is driven for the introduction of contaminated air into an intake opening 6. A liquid deodorizer in a deodorizer reservoir 9 is fed by a deodorizer feed pump 8 to a spray nozzle 5 which sprays and impregnates each of elements 4a and 4b of a deodorizing filter 4 with the deodorizer, where the contaminated air is passed through for deodorization and dust removal and the air thus purified is then discharged from an outlet opening 7. The air blower 3 is provided with an air blow amount switching means, while the deodorizer feed pump 8 is provided with a deodorizer feed amount switching means, hereby the deodorizer feed amount is changed-over in conjunction with the air blow amount.</p> |
