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.

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.

What Else Do I Need?

This question comes up a good amount when a customer calls in and asks about an EXAIR Product.   What else do I need in order to get this thing up and running.   It will depend some on the application the customer is trying to solve and some on the equipment the customer may (or may not) have in house, and some on how convenient and easy the customer would like to make the whole process. Let us look at the Industrial Housekeeping products, more specifically the Reversible Drum Vac Systems. (Mainly because this is the most recent product I have had a customer ask what else he needs to buy.)

The customer had already chosen a 55 gallon system (other systems available include a 30 and 110 gallon). When we look at the three different 55 gallon systems we offer, there is a clear difference in the number of items included in each kit.  The #6196 is a basic Reversible Drum Vac Kit.  For a unit like this, all you need to do is to provide a compressed air source and a tightly sealed 55 gallon steel drum. The picture below will show each item that is included in the kit.

If you are worried about some liquid spills on the floor and you would like to get some extra pick up tools and a dolly for the steel drum you are providing, then the #6296 Deluxe Reversible Drum Vac System is for you.   It will include everything from the basic system plus, a drum dolly, Spill Recovery Kit, magnetic tool holder, and extra plastic tools.  Again, the only items you will need to supply are the air compressor, and the tightly sealed 55 gallon drum.

6296

The final solution that EXAIR offers is everything you need, the whole kit and caboodle if you will. This kit prevents sourcing compressed air supply line and a closed top drum. It’s all in the box – with the exception of an air compressor. In the #6396 Premium Reversible Drum Vac System you will received the drum, everything in the Deluxe Kit, but some of the tools that were plastic get upgraded to aluminum tools.   This gives you the complete solution with a few clicks on our website.

6396

Throughout all of our product lines we give you the option to choose the best solution and most convenient package to get the problem solved quickly. We hold stock on all of our products (and accessories) so we can ship same day when we receive an order by 3:00 pm est.  We have the necessary accessories for you to get our units in and simply plug them in to your compressed air supply.  Why go to multiple sites or vendors when they are all in one place.
