Zebra AD has been supplying the Bulgarian military and citizens with gas masks for over 40 years now. Gas mask PG-1 was developed by our technical specialists at the start of the 1980s and we’ve been the sole manufacturer ever since.
Our PG-1 masks have Ø40 mm filter opening (Rd 40 x 1/7”) with EN 148-1 standardized threading, which accommodates various EN 14387 filters. The choice of filter depends on the type of protection needed – against the harmful effects of bacteria, viruses, poisonous substances, radioactive dust, ammonia, gases, etc. We equip our gas masks with combined filters manufactured by the Czech company MPL: Combined filter T25 – ABEK2Hg P3 R and Particulate filter T30 – P3 R.
The masks have a special diaphragm that enables voice communication. They are easy to adjust and comfortable to wear thanks to the five point harness of elasticated head straps. The mask material is non-allergenic and doesn’t cause skin irritations.
Each PG-1 set includes:
● facial gas mask
● combined filter canister
● carry/storage bag
Our gas masks are available in 3 sizes – 1 for children and 2 for adults:
