What is the Pre-Filter Cyclone Accumulator?

You may ask yourself: what is that strange thing on the side of some Vaniman dust collectors?

The Accumulator is Vaniman’s very own cyclone pre-filter. It separates particulates from the air before getting into the filter, which provides a number of benefits (described below).

The attached dust collector pulls the air into the cyclone pre-filter’s vortex, forcing heavier particles to fall into the Accumulator’s bucket. This bucket can easily be detached and emptied periodically.

By reducing the amount of material the dust collector has to clean, the Accumulator will extend the life of the filter and the unit itself.

How does it work?

Air and dust from the workstation enters through the side port of the Accumulator. Its unique shape forces the air to swirl, and creates a cyclonic vortex.

This vortex allows the air to separate. Dust particles drop to the bottom, and cleansed air escapes through the top port and through the hose, towards the dust collector — leaving behind 95% of dust particles.

That dust accumulates in the bucket at the bottom, which can be unlocked and emptied of its contents.

Benefits:

Save money on filter bags

The cyclone pre-filter helps to save money by lengthening the life of the dust collector’s filter or filter bag. By capturing the vast majority of the dust particles before they reach the dust collector, the filter bag can be used solely for the percolation of small particles. The filter bags will not become full as fast, saving money otherwise spent on replacements.

Save time on maintenance

The bucket on the Accumulator is a breeze to empty. With no replaceable parts, there are no parts to ship and fewer bags needed for replacement. There is less time spent opening the unit, which means less down time.

Extend the motor life

As a filter bag becomes fuller, the motor has to work harder to pull the air through the congested bag. The overworked motor will overheat and can even pop the thermal fuse. Extended use at these rough conditions will decrease the life of the brushes and the overall life of the motor.

When should I use a cyclone pre-filter Accumulator?

Heavy dust collection

In applications such as sandblasting, an Accumulator is a must. Excessive amounts of heavy material in a filter bag can cause it to fail and allow dust particulates into the motor, causing failure. With a cyclone pre-filter Accumulator, the dust collector’s filter is needed to capture only the smallest of particulates for which it was specially designed.

Collecting precious metals

The cyclone pre-filter provides an easy way to collect precious metals. While using a high speed hand tool on jewelry gold, a dust collector with an Accumulator will save the gold dust and allow it to be easily extracted.

More technologically advanced industries benefit as well. Expensive coating materials (such as those used by the aerospace industry in a Vaniman sandblaster) can be reclaimed, providing big savings for the user.

Automation

In large scale food producing operations, Accumulators have been used to protect regenerative blowers. The blowers are used to move food products along the line, but can easily get clogged due to loose debris from the food. Installing Vaniman Accumulators in line with the blowers captures that damaging debris. The low tech solution for the high tech problem saves companies money and headaches by reducing repairs and down time of the blowers.
