Weha Filter Project 13-Foot Dust Collection Booth

The Weha Filter Project 13-Foot (4-Meter) Automatic Self-Cleaning Dry Dust Collection Booth is designed for heavy-duty use in stone fabrication shops. Constructed of stainless steel, the system is designed to capture airborne dust generated from granite, marble, engineered stone, quartz, quartzite, fiberglass, ceramic, porcelain and other materials.

The booth draws air horizontally from the work area and downward toward the bottom of the unit, helping pull airborne dust away from the work surface and into the filtration system. According to the supplied product information, this downward airflow design helps move dust away from the operator's face and work area.

How the Dust Collection System Works

Specially designed cloth filter sleeves are installed inside the dust collector. When the system is operating, powerful motors create a vacuum that pulls airborne dust horizontally from the workbench area, downward toward the bottom of the wall and into the collection unit.

The filter sleeves capture dust while filtered air exits through the top of the dry dust collection booth. Collected dust settles into the catch-basin drawers at the bottom of the system for removal.

Depending on use, the supplied product information recommends emptying the collected dust from the catch basin daily or approximately once per week.

Automatic Self-Cleaning System

The Dust Collection Booth features an automatic self-cleaning system that uses compressed air from a pressurized tank. A series of membrane electrovalves and blowing tubes inside the cloth filter sleeves are controlled by an automatic sequencer.

After the dust collector is turned off, the system automatically runs an air-cleaning cycle that blows accumulated dust from the filter sleeves. The released dust then settles into the collection drawers at the bottom of the unit.

Filter Sleeve Maintenance

The supplied product information recommends removing the filter sleeves after approximately six months to one year, blowing them out and washing them with water. Allow the sleeves to dry before reinstalling them.

When the dust collector begins losing vacuum power, the supplied product information indicates that the filter sleeves may need to be replaced. Sleeve replacement is performed by loosening the retaining clamp and sliding the sleeve off.

Dust-Capture Information Note: The supplied product information contains two different dust-capture figures. One section states that the system is designed to trap 99% of dust, while another states that the cloth filter sleeves capture 99.99% of dust. Confirm the applicable filtration efficiency for this specific model before relying on a numerical capture rating.

Silica & Compliance Note: The supplied product information references OSHA silica requirements and describes the booth as an aid in removing silica-containing dust from fabrication shop air. It does not state that use of this equipment alone guarantees OSHA compliance. Confirm applicable workplace requirements and operating procedures for the installation.

Operating Requirement Note: This system requires 220V (208V) 3-phase electrical service with a 30-amp breaker and a 90 PSI compressed-air connection supplying a minimum of 2 CFM.

Frequently Asked Questions

What size is this dust collection booth?

The supplied product information identifies it as a 13-foot, or 4-meter, dust collection booth.

What materials is it designed to collect dust from?

The supplied information lists granite, marble, engineered stone, quartz, quartzite, fiberglass, ceramic, porcelain, concrete, natural stone and other airborne particles.

How does the booth move dust away from the work area?

The system pulls air horizontally from the work area and downward toward the bottom of the unit before directing it through the internal filter sleeves.

Does the system clean its own filters?

Yes. It includes an automatic compressed-air self-cleaning cycle that operates after the dust collector is turned off.

What electrical service is required?

The listed requirement is 220V (208V), 3-phase power with a 30-amp breaker.

Does it require compressed air?

Yes. The supplied product information specifies a 90 PSI air connection with a minimum of 2 CFM.

Are filter sleeves included?

Yes. A complete set of dust sleeves is supplied already installed on the dust collector.

What extension enclosure is included?

A 3-foot (1-meter) extension enclosure is included. A 6-foot (2-meter) extension enclosure is listed as an optional configuration.

How often should the filter sleeves be maintained?

The supplied information recommends removing, blowing out and washing the sleeves after approximately six months to one year. Replacement may be needed when the system begins losing vacuum power.
