The smell of sour coolant tanks you can smell from the parking lot of a facility still haunts me in my sleep till this day. We all know the drill, you want to run your coolant for as long as possible because that liquid is not cheap! Especially if you have several machines or even hundreds! But the results of running them longer than you should often stink, (pun intended) they turn sour, the lubrication properties start to diminish and you do not get the benefits you once got! Not to mention chips and small fines (which the stinky bacteria collect upon) can start to clog the system up. Here at EXAIR we had the same problem in our machine shop, so we designed the EXAIR Chip Trapper and use them to this day!
There are some machines out there capable of cleaning the tramp oil and removing any chips or shavings, but these tend to be very expensive and not very effective. We tested a few different methods here at EXAIR in our machine shop. As a result of these tests we determined that the best foot forward would be to develop something ourselves. Enter the EXAIR Chip Trapper. Using either a standard or High Lift Reversible Drum Vac to provide the vacuum source, the Chip Trapper is capable of filling or emptying a 55 gallon drum in less than two minutes. It is able to pick up both the liquid coolant as well as any chips or shavings that are suspended in the coolant. The liquid is forced through a filter bag inside of the drum which contains any solid materials while allowing the coolant to filter out into the drum. Switching the knob on the Reversible Drum Vac and the directional flow valve to empty will allow the clean coolant to be pumped back out of the drum and reused.
Here is a great overview video of the Chip Trapper Set up and operation!
The Chip Trapper is available in either 30, 55, and 110 gallon systems. It’ll also come with (2) 5 micron filter bags, other filter bags are also available ranging from 1 micron up to 200 micron filtration. Using a simple detergent, the filter bags can be washed out, cleaned, and reused multiple times. With no motors or impellers to clog or wear out, as well as no electricity requirement or shock hazard, the Chip Trapper comes with our standard 5-year Built to Last Warranty. Do yourself (and your machine operators) a favor and get a Chip Trapper on order today. They’re in stock, ready to ship and start saving you time and money!
Compressed air is a very versatile utility that can be used for applications in cooling products to cleaning off workspaces and products. That is where OSHA 1910.242(b) comes into play; this OSHA standard states that compressed air used for cleaning shall not be used except were reduced to less than 30 psi and then only with effective chip guarding and personal protective equipment. This standard is in place because in the event a dead end occurs, the static pressure at the main orifice can potentially force the high pressure air into someone’s bloodstream and cause an air embolism, which if left untreated can impede the flow of blood in the body and lead to a fatality.
Keeping that in mind there are two ways you can go about these cleaning applications and still stay in compliance with the OSHA standard. The first way is to regulate the air pressure in your pipe down to below 30 psig. But for the majority of applications this is not an effective solution as pressure does equate to the amount of force that can be produced from the system. The second solution is to use a nozzle that is engineered in a way the it cannot be dead ended. This means that the nozzle is designed in a way that no matter how hard you try the air coming out of the nozzle will be ejected into the atmosphere and not through skin.
Take EXAIR’s Air Nozzles for example, the fins and orifice placement are designed in a way that allows air escape air into the atmosphere. Once air has exited an orifice into atmospheric conditions the pressure becomes 0 psig but retains the velocity and higher volume from the higher compressed air inlet pressure which produces force.
In addition, OSHA 1910.242(b) also talks about the use of effective chip guarding, which simply means some method or equipment shall be installed that prevents particles from flying back and hitting the operator. If you look EXAIR’s Safety air guns you will notice that we offer Chip Shields. By simply adding “-CS” to the end of a part number for a Safety Air Gun you can help prevent injuries from flying particles in blow off applications.
If you have any questions or want more information on compressed air safety and OSHA related standards. Give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.

If you need to fill -and empty – a drum with water, or water-like liquid quickly and easily, there’s really no quicker – or easier – way to do it than the EXAIR Reversible Drum Vac. They’ve been around for decades, and are successfully used in a wide variety of applications. The Reversible Drum Vac pulls a -96″H2O suction head on a 5, 30, 55, or 110 gallon drum, which makes it ideal for a number of typical Industrial Housekeeping or fluid handling applications.
In cases where the liquid has a higher viscosity, or is below grade, the High Lift Reversible Drum Vac was developed with those exact situations in mind. It generates a -180″H2O suction head, and comes with a 20ft vacuum hose. Since its introduction, the High Lift Reversible Drum Vac has been successfully implemented in numerous uses where the extra suction head has been key:
A maker of bottled condiments (think barbecue sauce- or ketchup-like consistency) uses them to clean up accidents when bottles are overfilled, or a conveyor malfunction results in dispensing a bottle’s worth of condiment when there’s not a bottle under the nozzle. The 20ft hose gives them the reach to service several production lines from one centrally located drum, and the two way pumping action allows them to easily pump the drum into their waste collection system.
A precast concrete company uses one for various cleanup applications. The High Lift RDV‘s suction head is needed, in particular for their hydraulic oil leaks & spills.
A ferry operator uses one to clean out the engine room bilge. They put the High Lift RDV on a deck above the engine room…the 20ft hose extends down to the bilge to pump it out, and when the drum is full, it reaches to the main deck so the drum can be emptied into their waste recycling company’s receptacle.
A construction company uses one to clean up the slurry created during concrete cutting operations. The High Lift RDV is able to keep up with the slurry from even their largest saws, and the 20ft hose allows them to keep the drum conveniently out of the cutting area.
EXAIR Corporation has a variety of Industrial Vacuums to meet most any cleanup need. They’re all compressed air operated, which means they have no electric motors to burn out, or moving parts to wear out. If you’d like to find out more, give me a call.
EXAIR has a variety of Industrial Housekeeping products for your specific applications. Let’s explore the capabilities of our Reversible Drum Vac (RDV). The RDV is a safe, maintenance free system that is purpose built to recover liquids, oils sludge and chips from machine sumps. Since it is reversible, it will also fill your sumps from a fresh drum of machining fluids. This system does not require electricity and runs on compressed air. The RDV is maintenance free as it has no moving parts.
The RDV comes in 2 models which includes a “High Lift” version of the RDV and creates a maximum lift up to 15 feet of water column. The RDV comes in 4 capacities of 5, 30, 55 and 110 gallon drums while the High Lift comes in 30, 55 and 110 gallon drums. Let’s now focus on the RDV and the options for purchase.
The first thing to consider when purchasing your RDV is the capacity which I just mentioned of 5, 30, 55 and 110. Once you decided the capacity we have 3 models to choose. The Model 6196 is your basic model and comes with the vacuum unit, stand pipe, vacuum hose and aluminum wand. It is the basics of what you need to empty and fill your machine sumps.
The model 6296 is the same as the 6196 but also includes drum dolly, ABS spill recovery kit, tool holder and all tools.
The model 6396 is includes everything as describe with the Model 6296 but also includes the drum, drum dolly, upgrade to heavy duty aluminum tools, ABS spill recovery kit, tool holder and air hose.
