Everyone knows the basic steps to run a bag filter—but the small, easy-to-miss details are what make or break its performance (and your safety). Skip these, and you’ll end up with leaky filtration, short-lived filters, or even hassle. Here’s the down-to-earth guide:
- Inspect Before You Hit “Start”
Don’t just flip the switch and walk away. Spend 2 minutes checking two critical things first:
Cleanliness: Wipe out the filter housing and check the bag—if there’s leftover dust or gunk from last use, pre-clean them. Dirty starts mean your first batch of filtered material is already ruined.
O-rings (seals): Pinch the O-rings gently. If you see cracks, nicks, or they feel stiff, replace them. A bad seal = leaks, and leaks mean unfiltered stuff slips through—what’s the point of filtering then?
- Watch the Pressure Gauge (It’s Your Filter’s “Voice”)
The pressure gauge tells you exactly when your filter needs attention—ignore it, and you’ll regret it. Here’s the quick rule:
Startup: Normal pressure is around 0.05MPa.
During use: As the bag traps gunk, pressure climbs—usually stays between 0.1MPa and 0.3MPa.
Stop immediately: When it hits 0.4MPa, shut down. That’s the bag screaming “I’m full!” Running past this risks clogs, broken filters, or even leaks.
- Clean Smart, Not Hasty
A dirty filter is useless—but cleaning wrong ruins it faster. Stick to two simple rules:
Clean on a schedule, not when it breaks: If you use the filter daily, set a weekly clean; light use? Monthly. Waiting till it’s clogged means rushing through cleaning, missing gunk, or tearing the bag.
Don’t manhandle parts: Follow the disassembly steps—don’t yank the bag out or force the housing closed. Rough handling bends parts or tears bags, and replacement costs add up fast.
These tips aren’t fancy—they’re just common sense. Stick to them, and your bag filter will run steady, filter well, and last way longer. No tech degree needed—just a little attention to detail.
