Why am I experiencing a dramatic loss of suction at pick up points?

This should be treated as if your car’s engine light has come on. There can be many reasons for this and should be checked by a KTM Service Technician to determine the cause. Often it could be as simple as loose fan belts but there may be other contributing factors.

I have a pulse cleaning unit and my compressor is constantly running and can’t keep up with the demand. Why?

This indicates a problem with the pulse cleaning system. It could be as simple as a broken diaphragm supply line or require a replacement of worn solenoid and diaphragm moving parts. Faulty timer boards can also be a culprit. A KTM Service Technician can diagnose the problem and get your equipment running. We can then provide an itemized replacement parts list to keep it running.

When I shut the dust collector off a large amount of dust falls out of the rotary valve even with the valve not running. Why?

This usually indicates the rotary valve wiper blades are worn and in need of replacement. When the dust collector operates with worn rotary valve wipers, it also reduces suction at the pick up points where needed and allows the filters to build up resistance quickly by not allowing the dust to settle out in the hopper as intended.

When I start the system I get a puff of dust from the exhaust stack and then it clears up. What's happening?

This indicates that there is a breach in the sealing between the clean and dirty side of the system. It could be a small hole in a filter bag, a poor seal between the bag and tube sheet or a hole or gap in the tube sheet itself. A visual inspection by a KTM Service Technician can spot the obvious problems and correct them. Then KTM will introduce a quantity of our florescent Leek Seeker Powder and inspect the system with a special black light designed to highlight the powder that leaves traces around the leaking areas.

I think there may be some filters that are leaking. I don’t want to replace all of the filters but how do I find out which filters are leaking?

Often just a few filters will start to leak as a result of usage and nobody wants to replace all of the filters. Our specially formulated leak detection powder, DustChaser™ , will help you to find those troublesome leaks in your filters.

By injecting DustChaser™ leak detection powder into your baghouse, the DustChaser™ powder travels through the bahouse. When you use our black light, Baby Blue Plus+, the DustChaser™ powder quickly and efficiently pinpoints leaks in the bags, seams and welds.

DustChaser™ powder is 100% non-toxic, safe for personnel to handle, and environmentally green.

Since plastic pipe is cheaper than metal spiral pipe, can I use it on my dust collection system?

Plastic  pipe is NOT considered suitable for any dust collection system for several reasons:

1. Plastic pipe is non-conductive and allows the build-up of static electricity that can discharge causing shock that can harm employees and equipment. The most serious result is the risk of explosion and fire. Dust particles moving through the pipe have the potential to explode and start a fire from a spark that results from the static electricity created by the plastic pipe.  To minimize the fire potential,  requires grounding the plastic pipe - something that is expensive and off-sets the savings of using plastic pipe.

2. The design of the piping for maximum efficiency cannot be accomplished with the lack of plastic pipe fittings available.

3. Plastic pipe elbows are designed with a short radius that impedes air flow efficiency and results in material clogs that minimizes the efficiency of the entire dust collection system.

Metal piping, usually in the form of spiral steel pipe, has none of the above disadvantages. Spiral piping is conductive and easy to ground eliminating the build-up of static electricity.

There is a wide variety of fittings available to accommodate any size of piping.  Elbows are designed with long radius to minimize clogging - cleanouts and quick disconnects are available to ensure that cleaning can be done quickly and easily.

Word of Advice - check with your local municipality and fire department since using plastic piping may be a violation.  You should discuss your insurance provider.

I need to do a leak test on my dust collector, but what colour of KTM™ DustChaser™ leak detection powder should I use?

KTM™ DustChaser™ leak detection powder is available in a wide variety of colours - the colour you should use depends on the type of dust you are dealing with.

A good rule of thumb is:

Pink - good for all industries;

Orange - good for all industries except those where iron oxide (rust) is present;

Green - good for aluminum, cement, and utility industries and a good contrast where pink or orange has been previously used.

Yellow - good for all industries except those where sulphur is present such as cement, lime, asphalt, utility, and cogeneration plants.
When used with our ultra-violet light, KTM™ Baby Blue Plus+, our dust chaser system is completely foolproof, non-toxic, non-relative and simple to use.

Our system works for wire-cage, shaker, reverse air and cartridge-type collectors and is designed to ensure proper installation of new filters.

I want to do a leak test on my dust collector but am unsure of how much KTM™ DustChaser™ leak detection powder I need?

The amount of KTM™ DustChaser™ leak detection powder you will need is determined by the square footage of filter cloth your dust collector has - for 1,000 square foot of filter cloth, you will need 1 lb. of leak detection powder.
