Blind Hole Cleaning Systems

The compressed air blind hole cleaning system is used to clean out deep holes that external air blow-off systems might not be able to reach. The cleaner tube is inserted into the hole and then compressed are is blown through it dislodging any loose material and blowing it up the hole. The outer part of the cleaner seals with the hole being cleaned and the waste material is then conveyed into the collection bag.

A variety of different length blowing tubes can be deployed so the system can be optimised for each application.

Removing debris from blind or deep holes is an important yet risky task Nozzles have typically been used to blow into deep holes splashing out waste and making a mess in automated systems, and where manual effort is used, it makes for a messy and dangerous operation requiring protective gear to avoid injury. The compressed air blind hole cleaning system was developed for the purpose of improving safety and minimising or eliminating a mess. Some systems have appeared where a nozzle blows into a deep hole and a vacuum then draws the material removed to be taken away. However that does not work very well because you fight the blowing action with the vacuum action.  This new system uses only a powerful blowing action and uses a Venturi effect to draw out dust and debris from deep holes in drilled parts that are hard to clean safely.

It is designed so that the hole is completely covered to address safety issues while compressed air is blown into the hole through specially designed nozzles.  In this way, all the material in the deep, blind hole ends up in an attached, removable collection bag. No material is blown around the part or facility allowing for a cleaner, and safer, cleaning operation.

EXAIR’s Deep Hole Vac-u-Guns offer a low cost solution to quickly remove chips and contaminants from grooves, containers and drilled holes. The Deep Hole Vac-u-Gun is ideal for extracting chips/contaminants from grooves, containers and drilled holes where blow guns could create potentially hazardous flying debris.

Simply position the Deep Hole Vac-u-Gun over the hole and press the trigger. A small blow tube dislodges and lifts the chips while the large suction tube vacuums them away. The operator is protected from flying debris since all contaminants are contained within the clear suction tube. It is perfect for cleaning holes up to 1-1/4″ (32mm) diameter at a depth of 18″ (457mm).
