3 Things to Look for in Air Knives

We recently expanded air knives and after exhaustive training and research I wanted to pass some knowledge to our community. For those of you who don’t know an air knife is a non contact method of drying used primarily for drying and debris removal. This is done by focusing compressed air through small outlet channel, to produce a sheet of high pressure air flow.

Some of the things to consider when choosing an Air Knife:

1. Size: One plant uses air knives to clean bottles coming down a manufacturing line, while another uses several of them in series to dry the paint on vehicles. So, it’s important to have an idea for the amount of surface air that needs to be covered.

2. Air pressure Velocity:  This may seem like common sense, but the further you position the air knife from the actual item the lower the blow off pressure. While blow off pressure is important, the distance the unit will be placed from the subject material can be even more important.

3. Noise: Not all air knives are rated for OSHA noise specifications, trust me you do not want a loud whistling sound piercing your ears every time you turn the system on.

It is also important to make sure you have an air compressor that can supply the 100 PSI the air knife needs to effectively function.

3 Things to look for when Pressure Washer Shopping:

Pressure washers are a fast and efficient way to clean, treat or prepare almost any surface. But you may be getting bogged down in the details when deciding which one will be best for you. While building the web-pages for our pressure washers, I learned there are really only 3 main things to consider when shopping.

1. Fuel: What fuel would be easiest to power your system should be the first choice. Electric models tend to last longer, because they have less moving parts. On the other hand Gas and Diesel powered pressure washers generally provide more power (psi).

2. PSI: This basically means the force of the water comes out of the washer. PSI will determine whether the unit is used for light duty (car washing,) or heavy duty (striping the bark from trees.)

1300-1800 PSI

2000-3000 PSI

3000-4000+ PSI

Light duty, less frequent jobs (Car washing, shutter cleaning, spot cleaning) Heavy duty, more frequent jobs (Deck and pavement cleaning, sidewalks) Very frequent, heavy cleaning jobs (Industrial cleaning, concrete pavement, siding, paint stripping)

3. Hot vs. Cold Water: Cold pressure washers are ideal for removing dirt. However, if the surface you are cleaning is mixed with oil or grease, a cold water pressure washer won’t clean as well as a hot water pressure washer.
