30′ Long Super Air Knife

Earlier this month, I got a call on a Wednesday afternoon from a gentlemen at a sawmill in the Pacific Northwest. He indicated that they had a saw machine that was 30′ long, and it had a special scanner system to detect problems with the cutting which ran the full 30′ length.  In a sawing operation, there is sawdust and chips, and they can adhere to any surface including the scanner window.  When the debris would build up, the scanner system would give off false detection signals and cause issues with the operation.  We discussed the Super Air Knives as a way to blow off the scanner window, and be able to cover the entire 30′ length.  He asked for a quotation for a 30′ long Super Air Knife (and that doesn’t happen very often!)  And oh, by the way, delivery was needed on Friday (in 2 days!)

EXAIR manufactures Super Air Knives in lengths up to 108″.  To get to 30′, we looked at using (3) 108″ and (1) 36″ length.  Due to the length, the 108″ have to ship by freight truck, while all of the other lengths can ship via UPS or Fed Ex.  Since the customer was needing an overnight shipment, we had to take this into account.

We settled in on a system of (6) 54″ and (1) 36″ Super Air Knife. An added benefit to this arrangement was to allow the individual control of operation of the units, with each length blowing for a short duration, on down the line, until each had cycled.  This kept the instantaneous air consumption to a reasonable level, instead of 1 very large demand for cleaning the whole 30′ at once.  A quotation was sent out Thursday morning.

We received the order Thursday afternoon, shipped it later that day, and it delivered to the customer the next day on Friday. Installation occurred over the weekend.

The following Tuesday, I got an email – first to thank us for working so quickly from inquiry through to delivery for the 30′ of Air Knives, and then to ask to place another order for exactly the same set.  Turns out, there is a right edge scanner and a left edge scanner, and they were ready to do the other side.  We had a little extra time, and shipped out the full set a couple days later, and standard shipping still got to them before they were ready to install.

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.
