Wet-Dry Vacuum Converts Without Tools in 15 Seconds or Less!

In a recent video, I showcased our newest Industrial Housekeeping product, the EasySwitch Wet-Dry Vac. Throughout my years in metalworking as well as homeownership, I have honestly never used a wet-dry vacuum that is this easy to change operating modes from wet to dry or vice versa. So just how easy is it?

EasySwitch Wet-Dry Vac Mode Change Instructions

When writing out instructions on how to do this it takes a total of five steps for either direction. These five steps can easily be completed in less than 15 seconds and best of all, it is tool-free.

When changing over other wet/dry vacuums, whether it is a traditional electric vacuum like you may have at home or another pneumatic industrial vacuum on the market, the switchover process is cumbersome. There are typically fasteners or retainers that are necessary to hold the filters in place, filters can be poor quality and get damaged easily.  Small parts needed to hold filters in place like springs or retainer nuts can easily be lost, hard to manipulate and take additional time changing from liquid to dry modes or vice-versa. With the EasySwitch, the only fastener is a rubber latch that is attached to the filter hatch cover. This means operators can’t lose parts because they are all attached to the EasySwitch Lid. To convert from a dry vacuum to a wet vacuum the steps are simple.

  1. Turn off the compressed air and unlatch the rubber handle. This makes it possible to complete step two.
  2. Lift the filter hatch lid and let it rest on the hinge stop. This is all designed to be robust enough to easily support the weight of the EasySwitch unit as well as the air hose attached to it.
  3. Lift the filter, whether it is the HEPA rated filter or the standard filter, up and out of the lid.
  4. Close the filter hatch lid onto the edge gasket that stays firmly in place.
  5.  Latch the rubber handle/latch back into place and start processing liquid as needed.

That’s it, it takes less than 15 seconds in the video below (see it at 1:15) and I am pretty sure a speedcuber or cup stacker could do it even faster. Don’t believe me, want to test it out for yourself, we honor a 30-day guarantee on stock products. Get the EasySwitch Wet-Dry Vac in your facility and put it through your own rigorous testing. If it doesn’t perform to your liking, let us know and we will arrange for sending it back. Converting the vacuum from dry to wet isn’t the only thing that is fast, we also ship same day on orders for stock products (hint: all EasySwitch vacuums are stock product) received by 3 PM ET that are shipping within the US. (2 PM ET for orders billing and shipping to Canada.)

Super Air Amplifiers Provide Safe Air During Mine Rescue Missions

I have recently had the pleasure of working with a customer developing a method of delivering air to trapped miners during a multi-man mine rescue mission. The federal government mandates that in the event of an explosion, miners must have a safe place to retreat for a minimum of 96 hours. This system will provide them with a supply of air during that period of time. In the initial stages, they had tried using some old venturis left over from a previous project. While this did work, they weren’t as effective or efficient as they needed. Through a little bit of research, they found EXAIR.

Generally, the Super Air Amplifier utilizes a source of compressed air. In this case, instead of using compressed air as the source, they’re using cryogenic liquid air. That air passes through a series of cold plates and heat exchangers and gets to the Super Air Amplifier at about 70°F. This air is then carried into the chamber, giving the miners a source of clean air.

EXAIR Super Air Amplifiers utilize a patented shim design that allows the unit to entrain ambient air at a rate of up to 25:1 from the compressed air supply. This balanced outlet airflow minimizes wind shear, producing sound levels that are typically three times quieter than other air movers. The Super Air Amplifiers are supplied with a .003” slotted air gap and can be adjusted by replacing the shim with a thicker .006” or .009” shim or by regulating the air pressure supplied to it. In addition to making gross adjustments to the airflow by changing the shim thickness, flow can also be dialed in by regulating the air pressure supplied. All Super Air Amplifier Kits come complete with the a properly sized Auto-Drain Filter to keep the air clean and dry, a Pressure Regulator to “dial” in the airflow, and a shim set. When the filter is installed just upstream of the Super Air Amplifier, there is no need to perform any regular maintenance. With no moving parts to wear out, you can expect many years of reliable operation.

Video Blog: EXAIR’s New EasySwitch Wet/Dry Vac Operation

EXAIR introduced our first Wet/Dry Vacuum in August. We have simplified the process of converting a vacuum from wet to dry (and dry to wet) materials. This can now be easily switched within 15 seconds due to its patent pending engineering and design. The video below is a quick rundown of just how easy it is to contain any industrial mess with the new compressed air powered vacuum from EXAIR.

If you would like to discuss the EasySwitch Vacuum options and kits available from stock, please contact us.

Compressed Air Amplifiers Outperform Fans for Cooling Parts

When seeking a suitable solution for cooling or drying your parts, you may be tempted to try out a low-cost fan to get the job done. While fans do a great job of keeping you cool during the warmer months, they’re not the best choice for cooling or drying parts. Have you ever noticed that when standing in front of a fan the flow pattern is not consistent? This is due to the nature in which the fan blades create that air flow by “slapping” the air as they spin rapidly. The air flow that exits from the fan is turbulent and is not as effective as the laminar air flow pattern that is produced by EXAIR’s Super Air Amplifier. The Super Air Amplifier utilizes a patented shim design that maintains a critical position of the air gap and creates a laminar air flow pattern that will exit the outlet of the unit.

In addition to providing laminar air flow more conducive for cooling and drying, the Super Air Amplifier provides much more air that can be directed at the target. A standard 2.36” x 2.36” DC operated fan provides anywhere from 12-27 CFM at the outlet, depending on the model. For comparison, a Model 120022 2” Super Air Amplifier will provide 341 SCFM at the outlet when operated at 80 psig. At just 6” away from the outlet, this value increases to 1,023 SCFM!! When compared to the fan outlet air flow, the Super Air Amplifier produces more than an 1,100% increase in air volume!

When replacing a fan with a Super Air Amplifier, the process time can be dramatically reduced. The increase in air volume significantly reduces the contact time that your part will need to be exposed to the air flow, allowing you to increase your line speed and decrease the overall production cost of the part. This is achieved due to the nature in which a Super Air Amplifier draws in air from the ambient environment. At amplification ratios as great as 25:1, the Super Air Amplifier is the best way to move a lot of air volume across the part with very little compressed air supplied to it. Check out the video

In addition to providing laminar airflow and increasing the volume of air, the Super Air Amplifier is also infinitely adjustable through one of two ways. Each size Super Air Amplifier has a shim set that can be purchased. Swapping out the stock shim for a thinner shim will reduce the compressed air consumption, force, and flow. Installing a thicker shim will increase it. Additionally, the force and flow can also be adjusted by regulating the input supply pressure through the use of a pressure regulator. With sizes ranges from ¾” up to 8”, there’s a Super Air Amplifier for all applications. Give us a call today to see how you can optimize your process by replacing your fans with one or more Super Air Amplifiers.
