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.

To discuss your application and how the EXAIR Industrial Housekeeping Products can be a benefit at your facility, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.

“Deluxe” and “Premium”

These are two words that have been important parts of my vocabulary for most of my life. As a long time fast-food burger connoisseur, these words mean I’m getting something other than a hastily cooked ground beef patty on an enriched white flour bun that may or may not have been sitting under a heat lamp for a specific period of time. If you’re anywhere near as familiar with drive-thru cuisine as I am, you’ll know that “Deluxe” usually means a variety of toppings has been added to an otherwise relatively plain sandwich…it’s been “run through the garden,” if you will. And “Premium” can mean anything from a special bun, gourmet cheese, up-scale meat, and/or the addition of bacon…they ALWAYS get me at bacon…

I don't know what the knife and fork are doing there, but whatever...

EXAIR’s Industrial Vacuums are also available in Deluxe and Premium Kits. Now, if you’ve already got a drum, our standard Kits will quickly and economically turn that drum into a powerful, fast, and efficient vacuum system, without the need for anything fancy. If you’re looking for complete, comprehensive clean up solutions, though, our Deluxe Kits add a drum dolly, a tool holder, and additional tools. The Premium Kits also include a durable steel drum and a set of Heavy Duty Aluminum Tools.

Whatever your needs are, we’ve got an efficient, quiet, durable, long-lasting, maintenance-free vacuum system for you. Our Reversible Drum Vac will empty…or fill…a 55 gallon drum in 90 seconds (tested with water.) Our new High Lift Reversible Drum Vac pumps that same 55 gallons in just 85 seconds, with up to 15 feet of suction head. Then, of course, the Chip Trapper uses our Reversible Drum Vac technology to filter and extend the life of your machine tool coolants, lubricating oils, etc.

For solids vacuuming situations, our Chip Vac picks up wet or dry chips, debris, etc., and deposits them directly into the drum. This is the function of the Heavy Duty Dry Vac as well. It’s more powerful than the Chip Vac, for use with heavier debris, and it’s made of a hardened alloy for superior abrasion resistance. The Heavy Duty HEPA Vac delivers the same high performance, with a high efficiency filter for total dust containment.

Whatever your Industrial Vacuum needs are, we’ve got a solution for you. And if you order before the end of March, we’ll throw in a FREE Vac-u-Gun…our lightweight and portable vacuum gun, blow gun, and transfer tool, all in one. Call me to find out more.

Don’t Waste Money On Your Waste Removal

Lately, we have been receiving calls from customers that are looking for a wet/dry vac that they are accustomed to seeing in the form of an electrical vacuum for their home work shop.  They call us wanting a general clean up vacuum for their shop.  The items they are looking to clean up are coolant, dust and chips.  Our solution for this is to run two vacuums, and most people are asking why can’t it do both.  The answer – cost.

Generally, people seeking EXAIR’s pneumatic vacuums already see the value in the durability of a vacuum with no moving parts to maintain or replace when comparing to electric vacuums. It is the simplest of dollar savings,  the longer the product lasts and is maintenance free, the more money you will save from the absence of repair parts or new vacuums. And electric vacuums are notorious for burning up motors and not lasting within tough industrial environments. You can read about additional features/benefits within EXAIR’s pneumatic vacuum line here and here, but I will talk about our products specifications in detail.

EXAIR has two categories of vacuum, wet vacs and dry vacs.  The original wet vac for vacuuming coolant, swarf, or oil is the Reversible Drum Vac (RDV), used to easily empty and fill coolant sumps quickly. The Chip Trapper features a filtration system which removes chips and debris that is within the coolant, keeping the coolant clean, extending the coolant life and minimizing surfaces for bacteria to grow.  The Reversible Drum Vac and the Chip Trapper Systems use 19 SCFM of compressed air at 80 PSIG of and can fill a drum with 55 gallons of water in 90 seconds. These workhorse vacuums will last many years and withstand the rugged treatment found in hardworking manufacturing facilities.

Drum Vac

In the other category of  our industrial vacuums are the “dry” vacuums.  This term “dry” is a little ambiguous, because the vacuums will be able to move some liquid.  For instance, the liquid coating a chip or spills on the shop floor can easily be picked up with the dry vacuums.  We have a number of dry vacuums available:  The Chip Vac is a continuous duty vacuum used for general cleanup around machinery. The Chip Vac drum lid assembly can be used from drum to drum to aid in separating and recycling materials. Our Heavy Duty Dry Vac is best for applications vacuuming heavy materials, abrasive medias or longer distance (20′). And the Heavy Duty HEPA Vac is designed to provide protection from airborne particulate and is suited for dusty environments.

Exair-heavy-duty-HEPA-vacuum

To compare EXAIR products with other pneumatic vacuums, let’s look at the Chip Vac (40 SCFM at 80 PSIG) and the RDV above (19 SCFM at 80 PSIG). Combining the two vacuums you would require (59 SCFM at 80 PSIG. If you search long enough, you could find a pneumatic vacuum that is advertised as wet/dry, but this ability comes at a cost.  The most obvious cost is the upfront purchase price, which is consistently much higher than the combined cost of the (2) EXAIR units.  Also the units range in air use from 68 SCFM to 110 SCFM.  That is up to 86% more air required!

Let’s assume that you did run both constantly.  The wet/dry vac will cost you $0.14 extra an hour to run, assuming that your compressed air cost is $0.25 per 1,000 SCF.  That is really an unfair comparison to our products though, because we could have (2) vacuums operating at different locations in the plant accomplishing twice as much work.  Even still the (2) EXAIR units will save $810 per year with 250 working days in a year and 24 working hours in a day.

$810 per year may not sound like to much to you.  What if we change the scenario? How much air can you save? Let’s say you run a large wet/dry vacuum, which consumes 110 SCFM, everyday for 8 hours over 250 working days. The wet/dry vacuum will use 52,800 SCF per day or 13,200,000 SCF per year.  This compress air will cost you $3,300 just to compress that air. By comparison, the Chip Vac will only cost you $1,200 per year to run in compressed air.  Using the Chip Vac instead of the wet/dry vac, will save you $2,100 per year. in compressed air operating costs.

How Fast is your Chip Trapper?

This question came up to me the other day from a customer in the automotive component industry in Monterrey, Mexico. He was interested in a “sump sucker” type of cleaner for his coolant. But he had one stipulation; he wanted to clean his coolant “on the fly” so to speak so he did not have to turn off his CNC equipment to facilitate the cleaning process.

His original inquiry involved a simultaneous in/out function of the coolant being processed through. We could not accommodate him with a machine that was quite in this nature. However, we do have a product that is the next best thing. Basically, as quickly as the coolant is sucked into the barrel of a Chip Trapper, it is being filtered and is immediately ready to be dispensed back into the machining center sump tank. There is one big benefit in doing it this way. That is the user can pull in all chips that accumulate in the fluid at one time to insure a cleaner end product when the coolant is pumped back into the tank. The other way, would involve recycling a lot of coolant that has already gone through the filtering process and so you end up wasting time re-filtering coolant that has already been processed once. If you have a product like Chip Trapper which is available in sizes to hold up to 110 gallons, you can suck all of the coolant out of the machine in less than 5 minutes so it can be filtered and put right back into the sump. The whole process could take place in as little as 10 minutes depending on how much cleaning in the sump area the customer prefers to do.

That means that a coolant tank could be emptied and re-filled again in as little time as it takes for an operator to go on break or to go to lunch. If you are pressed for time to get in and do coolant maintenance on a regular basis, then perhaps the Chip Trapper would be the answer to your maintenance and up-time concerns.
