I have blogged about this many times and we continue to help customers by using our free Efficiency Lab service that EXAIR provides to customers throughout the USA.  The EXAIR Efficiency Lab allows customers to send in their existing blow off device and we will test it for compressed air consumption, sound level, and force.  Ideally we try to take these measurements at the same operating pressure that is being supplied in the field so that we can compare it to an EXAIR product and offer the customer the best solution, the safest solution, and an engineered solution capable of saving them money through air savings and effectiveness.

Here is a recent example of  a product sent in by a customer concerned with compressed air consumption and safety of their people. The  hose they sent in was actually designed to be used with liquid coolants and was a very large consumer of compressed air.

A flexible blow off with .495" openings. Designed for liquid but used for compressed air. Enormous waste of air and a huge safety risk.
A flexible blow off with .495″ openings. Designed for liquid but used for compressed air. Enormous waste of air and a huge safety risk.

The hose shown above was being used at 40 psig inlet pressure.  The device is not OSHA compliant for dead end pressure, nor does it meet or exceed the OSHA standard for allowable noise level exposure.   The hose was utilizing 84.64 SCFM of compressed air and was giving off 100.1 dBA of sound.

OSHA Noise Level

As seen in the chart above, an employee is only permitted to work in the surrounding area for 2 hours a day when exposed to this noise level.   The amount of force that the nozzle gave off was far more than what was needed to blow chips and fines off the part.   The EXAIR solution was a model 1002-9230 – Safety air Nozzle w/ 30″ Stay Set Hose.

The EXAIR products were operated at line pressure of 80 psig which means they utilized 17 SCFM of compressed air and gave off a sound level of 80 dBA.  On top of saving over 67 SCFM per nozzle and reducing the noise level to below OSHA standard, the EXAIR engineered solution also meets or exceeds the OSHA standard for 30 psig dead end pressure.   In total this customer has replaced 8 of these inefficient lines and is saving 541 SCFM of compressed air each time they activate the part blowoff.

If you would like to find out more about the EXAIR Efficiency Lab, contact an Application Engineer.

We look forward to testing your blow off and being able to recommend a safe, efficient, engineered solution.

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.
