Overview

Incorporating pneumatic vacuum technology, the Guardair Blind Hole® Vacuum is designed to safely and effectively suck up debris normally trapped in blind holes. Eliminates dangerous chip fly-back and extra cleanup generated by simply blowing out debris. Powered by standard shop compressed air, the BH4000 features a powerful pneumatic vacuum paired with an on-demand, air-agitator that loosens and lifts chips or debris lying deep within crevices or blind holes. The clear-view window ensures precision positioning for maximum performance, and the 5' vacuum hose provides flexible reach. Capable of mounting on any vertical surface, the versatile Blind Hole Vacuum is equipped with a 5.5 gallon, chemical resistant container and a standard air filter. 3/8" FNPT inlet.

What are the advantages of compressed air-powered vacuums over electric vacuums?

Compressed air-powered vacuums avoid motor burnout, eliminate electrical hazards, reduce Total Cost of Ownership, and offer higher suction power, especially for heavy materials.

What is the difference between Vacuum Flow and Vacuum Lift?

Vacuum Flow measures air volume through the hose, impacting debris movement, while Vacuum Lift measures the height a vacuum can lift materials, key for deep cleaning.

What is the definition of Vacuum Suction?

Vacuum suction refers to the general cleaning power of a vacuum unit. It is an off-hand way to describe a vacuum unit's ability to generate vacuum flow, vacuum lift, and its overall effectiveness to clean.

With respect to compressed air, what is the difference between Pressure and Flow?

Pressure is the measure of potential energy stored within compressed air and is measured in pounds per square inch (psi). Flow is the volume of air traveling through an air supply line or a vacuum hose during a given period of time; measured in cubic feet per minute (cfm).

How do vacuums generate static electricity?

Static electricity is created as air moves over the vacuum hose’s internal surface, influenced by air composition, humidity, and material type.
