Q: Ducting Material – Can I use HVAC ducting or how about PVC, it’s cheaper and looks like it can do the job?
A: It does look like it can do the job, but it can’t. HVAC duct is of a much lesser gauge than the ducting used in dust collection. Generally it cannot withstand the pressure and will “collapse” (According to some of our customers who have tried it, it’s not a pretty picture!!). PVC will generate generous amounts of static electricity, and therefore create a fire hazard. Rule of thumb…if you see lots of dust clinging to the bottom of your PVC ducting it is there because of static…otherwise gravity would have intervened.
Q: Filter Bag Maintenance – How do you maintain the upper filter bags?
A: Preventive maintenance is always the best method. Of course you’ll need to do a bit more if your Dustek is running 24/7 than if it runs several hours a week. If you run 24/7 you should “beat” the bags before turning the collector on in the morning and after you shut it down at night. A canoe paddle or similar works very well. Fringe benefit: I’ve been told it helps relieve stress.
Q: Filter Bag Cleaning – Can we clean the bags and how?
A: Yes you can. There are several ways of doing this. The most obvious and easiest is to take off the bags, take them somewhere outside, turn them inside out and beat them. Some customers use compressed air and tell me it works. Commercial Dry Cleaning is also an option. Buy a second set of bags and send the others to be dry cleaned. Generally Cleaning companies that clean uniforms, gloves, etc. will clean the bags as well. Washing – Somewhat Controversial…our manual tells you not to wash the bags yet a number of customers have done it with good results. The key here is to turn the bags inside out, get most of the dust out by beating them, and finding a Laundromat far away from your company or neighborhood!!
Q: Filter Bag Life – What’s the productive life of a Dustek Filterbag?
A: It depends on the kind of dust collected and the usage. All filterbags love wood shavings such as come from a shaper, planer, jointer or moulder….they’ll last longer than bags used primarily for fine dust. As a rule of thumb…you should plan to replace bags more often when you have fine dust applications such as wide belt sanders running 80 grit or higher, sealer sanders, etc. than you would if you run moulders, shapers, planers, etc. I consider this the cost of doing business and it applies to our dust collectors or to million dollars bag houses…..the concept is the same.
Q: Can you “prime” Filter Bags?
A: Yes you can. If your dust collector runs on let’s say a planer, jointer, CNC machining center and widebelt sander you run your planer or jointer for the first few hours with new filterbags. This provides the bags with a nice non-dense coating and will keep the fine dust from penetrating the pores too much.
