E-Vac Vacuum Generators- For More Than Just Pick and Place

A textbook application for vacuum generators is the ‘pick and place’ function.  With ever increasing automation and robotic cells, more and more opportunities present themselves to utilize the E-Vac Vacuum Generator as a part of the system to ‘pick up’ an object and ‘place’ it in a new position. But the E-Vac’s can be used for many more types of applications.

Another popular usage is to hold something in place. One of our customers uses an array of Adjustable E-Vacs to pull a vacuum and hold down various sizes of Styrofoam sheets during a machining operation. The previous system was a 1 hp blower type, and did not offer any flexibility for handling different size sheets. Sheets would slip and produce off quality results. After installing the new design, the system was able to handle any size sheet, and scrap levels went down dramatically.

A unique implication that was solved with an E-Vac was to deflate sporting balls.  The customer printed custom logos, and preferred the items to be flat for the printing operation. Using a commercial grade electric shop vac didn’t completely deflate the balls, and motors burned out often.  Using a low vacuum In-Line E-Vac with a quiet Straight Through Muffler, the customer can now quickly and quietly, fully deflate the balls.

Another popular use for the E-Vac is to pull a vacuum for drawing up liquids or gases. A customer that manufactures automotive seats was having issues with the process, where the expanding foam was producing a gas, and the gas would produce pockets and voids in the foam after setting.  The customer used a model 800017 In-Line E-Vac to create a vacuum inside the mold and draw off the gas, eliminating the pockets and the voids in the final product.

Lastly, as I am big fan of recycling, anything and everything, we worked with a customer that recycles the old CRT style of computer monitor  (remember those?) The housing would be sawed in half, so that access to the internal components could be made. Because of the variability in the size and shape of the monitors, the customer was using an adjustable chuck system, which took time to set-up for every monitor, each being a bit different. To speed up the process, an EXAIR In-Line E-Vac and 5″ Suction Cup was implemented, and the monitor held in place by the screen, which was was very consistent in shape from monitor to monitor. This change reduced the set-up time required.

These and other Applications for the E-VACs and all other EXAIR products can be found on the EXAIR website on the Products page, under the Related Info section toward the bottom of each page.

Taking My Job home With Me (I Wish!)

Last week, as Mother Nature was doing her typical dance between warm, almost Spring like days and then quickly reverting back to her Winter ways, the southwestern Ohio area was hit with a powerful storm. Luckily, my neighborhood area was spared the really strong winds and tornadic activity that nearby areas experienced.  We did however receive a decent amount of rainfall.

Every Spring when the ground is still slightly frozen, the first good rain always leads to some water  leakage into my basement.  The water comes in through the gaps between the floor and the walls and even seeps up through some of the floor cracks.  I have my theories as to why it only happens in the spring, but I’ll save that for another day.  As the blog title says, I wish I had taken home a Reversible Drum Vac with me.

EXAIR  manufactures the Reversible Drum Vac (RDV) System, which attaches quickly to to any 30, 55, or 110 gallon closed head drum. The Mini Reversible Drum Vac has the same great performance and comes complete with a 5 gallon drum.  Coupled with the Spill Recovery Kit, using the RDV to vacuum up the rain water would have been a short and simple process.  Using a mop, towels, fans and a dehumidifier took much longer and still did not get everything dry.

The compressed air operated Reversible Drum Vac System is a high powered vacuum that can fill a 55 gallon drum in less than 2 minutes, and with a simple turn of the a knob, the same stainless steel pump quickly empties the drum.  With no electric motor to wear out, or impellers to clog, the RDV is designed to work in industrial environments.  An automatic safety shutoff valve prevents the system from over-filling.

EXAIR also manufactures systems made for cleaning up solids, such as machining chips and other debris.

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.

If you find that your chip conveying system is affecting your operations, you should contact an Application Engineer at EXAIR to see if we have a better and more reliable solution to remove your swarf.
