Heavy Duty Pneumatic Vacuums: EXAIR’s Heavy Duty Dry Vac

Are you tired of not being able to pick up your heavier material with your current vacuum? Is your material abrasive, does it have a high bulk density? Are you tired of your electric vacuum constantly burning up its motor? EXAIR’s Heavy Duty Dry Vac system is engineered with the power to vacuum heavy materials, materials with high bulk densities. It’s material resists abrasion from the harshest of debris, like garnet, glass, tumbling media and steel shot. This system has no moving parts which means no motors or bearings that can fail on you.

The Heavy Duty Dry Vac requires only 68 SCFM at 80 psig of compressed air to operate. Using a hardened alloy construction for the vacuum generator gives the system an increased resistance to abrasive material including sand and blasting material. Depending on your application and the volume of material you need to vacuum we provide 3 different sizes, 30-gal, 55-gal, and 110-gal.  

Heavy Duty Dry Vac in operation

The design of the Heavy Duty Dry Vac allows the system to be mounted on your own drum and has a 0.1-micron filter bag installed on the center of the drum to allow air to escape and keep the material inside the drum. The enlarged size of the filter bag allows it to last longer before needing to be cleaned and/or changed out. Under the lid EXAIR has design features to aid in lowering the sound level down to only 82 dBA.

The Heavy Duty Dry Vac system comes in three different kits; these kits are the Standard, Deluxe, and Premium systems. The basic kit come with the Vacuum generator, the lid, and a lock ring to seal the lid onto your drum. The kit also includes the filter bag, 10’ Static resistant hose, and the aluminum chip wand. The basic system is everything that you need to get started with your own drum.
The Deluxe system Includes everything that the basic Heavy Duty Dry Vac system comes with but adds a few items: A magnetic tool holder, a 2-piece double bend wand, 12” floor tool, 11” crevice tool, 24” crevice tool, a skimmer tool with a detachable brush, and a 3-1/2” diameter bust brush with conductive bristles. All of the tools that come in the Deluxe system are of Aluminum construction. This system also adds the drum dolly to make it easier for you to move the system around.

If you do not have your own drum the Premium system includes everything Deluxe system does except adds a drum. Each Drum vac system comes in one of the 3 sizes listed.

Choosing the Right Dry Vacuum – Chip Vac or Heavy Duty Dry Vac

A common question we get from our customers is, ‘I need a dry vac, should I use the Chip Vac or Heavy Duty Dry Vac.’  This is very good question, and we will take the time to better understand the application in order to best answer that question.

Both the EXAIR Chip Vac and Heavy Duty Dry Vac are designed to turn an ordinary 5 (Chip Vac only,) 30, 55, or 110 gallon open top drum into a powerful, industrial duty vacuum cleaner. Both are powered by compressed air, and have no moving parts to wear out or break, whereas the typical electrically operated system has motors and impellers that clog and break down quickly.  The Chip Vac and Heavy Duty Dry Vac are also quiet, at half the sound level of electric versions.

The Chip Vac is designed specifically for vacuuming chips. It creates a powerful direct flow that is ideal for metal, wood, and plastic chips.  Because it has a filter bag, in can also handle the occasional dusty material, and keep the surrounding air clean.

If the operation machines different materials, the lid can be removed from one drum and moved to another, to keep the materials separate for easy recycling.

The Heavy Duty Dry Vac was engineered to vacuum more dry material in less time with less wear. The hardened alloy construction resists premature wear and the increased power makes difficult jobs and harsh environments more easily handled.

The Heavy Duty Dry Vac is ideal for abrasive materials such as steel shot, garnet, metal chips and sand, and is also useful for general purpose applications such as vacuuming floors, machines, work stations and machinery/equipment.

Like the Chip Vac, the Heavy Duty Dry Vac drum lid fits any open top drum, and can be moved from one drum to another facilitating recycling efforts.

Below shows the powerful performance of the Heavy Duty Dry Vac when considering large, heavy material and the increased performance you could expect.

EXAIR Chip Vac Removes Swarf and Keeps the Machining Center Running

The word of the day is “swarf”. Swarf is fine chips or filings of stone, metal or other material produced by a machining operation.

A company had four automatic profile cutting machines to cut aluminum stock.  They contacted me for help to improve their operation.  Each machine had a cleated belt conveyor to remove the swarf (or chips) from the cutting process.  Because the swarf was small in size, the chips could get around the edge of the belt and affect the conveying system.  Two of the four conveyors failed, and they wanted to find a better option to remove the swarf and keep the machines running.  They sent me a photo of the type and size of the swarf that was thwarting their conveying system.

EXAIR receives many calls about applications similar to this. I suggested the model 6193 Chip Vac System.  This assembly will fit onto a standard open-top 55 gallon drum which has a much smaller footprint than the conveying system.  The 0.1 micron filter allows for the air to escape and keep the fine particles inside the drum.  For this customer, once the drum was filled with aluminum chips, it was easy to rotate in an empty drum, sending the full drum of material to recycling.  The vacuum generator has no moving parts which makes it quiet, maintenance free, and long lasting.  It also creates a high vacuum level which was very useful when they attached it near the chip collection area.  The Chip Vac System was easy to install and it was very beneficial in keeping the machining area clean and running.

Compressed Air Vacs have Advantages Over Electric Vacuums – Durability, Reliability, Noise Levels

Have you ever heard an electric vacuum toward the end of its life? It gets this high pitch annoying noise caused by the bearings going out.  I spoke recently to a customer who was hearing it about every two months.   This company cuts ceramic tiles with a diamond-tooth circular saw.  During this operation, a lot of dust is being created.  He would attach an electric vacuum to the dust port of the saw housing.  The vacuum was to remove as much dust as possible from the sawing operation to keep the area clean and the operators safe.  After about two months of operation, they would start hearing that “moan” from their electric vacuum.  The performance of the vacuum started to drop off, and it would allow more dust to collect in the saw room.  This was a hazard as it would make the floor slippery.  The operators then had to stop operations early to clean the floors at the end of each shift.  After their second electric vacuum failed, they started looking for a better alternative.

When they contacted me about their issue, I knew immediately which EXAIR product would serve their need very well. I suggested our new model 6399-30, 30 gallon Premium Heavy Duty HEPA Vac system for this operation.  The 30 gallon size is the smallest in the Heavy Duty HEPA family which made it easy to fit behind the saw table away from the operators.  The HEPA filter inside has an efficiency of 99.97% at 0.3 micron.  So, the dust will remain in the drum and not migrate back into the ambient air.  The EXAIR vacuum generator has no moving parts or bearings to wear.  It is made from a hardened steel construction which is very resistant to wear and abrasion from materials like ceramic.  The EXAIR design can generate a high vacuum level to draw dust material at an extremely high rate, and it only has a decibel level of 82 dBA.  With clean compressed air, this vacuum will last for years and years; not months.

As this company installed the Heavy Duty HEPA Vac into their system, the first thing that they noticed was how quiet it operated. The constant loud noise from their electric vacuum was gone, making it a better working environment.  They also noticed that the dust was being removed very quickly by the powerful vacuum pressure.  This meant that the amount of dust that could collect on the floor and equipment was greatly reduced.  Since the floors were cleaner longer, it decreased shut down times and removed the constant hazard of a slippery floor.

If you find that you are going through your electric vacuums or just would like to reduce the noise levels, EXAIR has a large line of Industrial Housekeeping Products. You can contact us to see if we have the right vacuum product for you.
