Key Features
-
Complete 2-Filter Set: Primary (outer) 7221933 + secondary (inner/safety) 7221934. Both filters included — no separate purchases needed for a full air filter service.
-
Heavy-Duty Filtration: High-capacity cellulose/synthetic blend media designed for extreme dust loads in construction and agricultural operations.

Frequently Asked Questions
Q: Does this set include both filters?
A: Yes — 7221933 primary AND 7221934 secondary. Complete air filter service in one purchase.
Q: Can I just replace the primary?
A: Replace both for maximum protection. The secondary is your last defense if primary fails.
Q: How often should I replace?
A: Replace when restriction indicator shows red (250-500 hours). Replace secondary every 2-3 primary changes.
Q: Will this fit my Bobcat T770?
A: Yes. Fits all T-series track loaders, S-series skid steers, and A770 loaders.
Q: How do I know when to replace?
A: Check built-in restriction indicator. Never blow out paper filters with compressed air — it damages the media.
