Solberg 851 Polyester Filter Cartridge 8-3/4″ H 5-7/8″ OD 290 SCFM

Description

Product Overview

The Solberg 851™ polyester filter cartridge is a precision‑engineered component designed for demanding industrial vacuum pump systems. Constructed from high‑grade polyester fabric reinforced with epoxy‑coated steel wire on both sides, the media delivers a robust 5‑micron filtration efficiency while maintaining low pressure drop. With an 8‑3/4″ overall height, a 5‑7/8″ outer diameter, and a 3‑1/2″ inner diameter, the cartridge fits standard vacuum pump housings and provides a flow capacity of up to 290 SCFM. The cartridge is washable with lukewarm water and mild detergent, allowing multiple service cycles and reducing total cost of ownership. Its temperature tolerance ranges from –15 °F (‑26 °C) to 220 °F (104 °C), making it suitable for a wide variety of process environments.

Usage

Designed for industrial process filtration, the Solberg 851 cartridge excels in applications such as metalworking shop vacuums, chemical processing exhaust systems, and high‑volume dust collection units. The cartridge’s high flow rating and low differential pressure enable continuous operation without frequent shutdowns for filter changes. It performs reliably in harsh conditions, including exposure to oily mist, fine metal particles, and abrasive powders. Users in manufacturing, automotive, aerospace, and laboratory settings benefit from its ability to protect downstream equipment, improve air quality, and meet regulatory standards for particulate emissions. The washable design simplifies maintenance: operators can remove the cartridge, rinse it, and reinstall it, extending service life while minimizing downtime.

FAQ

What is the recommended cleaning procedure for the Solberg 851 cartridge?

Remove the cartridge from the pump housing, rinse it with lukewarm water, and gently scrub with a mild detergent if needed. Rinse thoroughly, allow it to air‑dry completely, and reinstall. Avoid using harsh chemicals or high‑temperature water, as they can degrade the epoxy coating.

Can the cartridge be used with filters other than vacuum pumps?

Yes, the 851 cartridge is compatible with any filtration system that matches its dimensions (8‑3/4″ height, 5‑7/8″ outer diameter, 3‑1/2″ inner diameter). It is commonly employed in dust collection units, air handling systems, and process exhaust applications where high flow and fine particle capture are required.

How often should the filter be changed or cleaned?

Cleaning frequency depends on operating conditions. In typical industrial use, a visual inspection every 30‑60 days will indicate when the differential pressure approaches the 10‑15 in H₂O range. At that point, clean the cartridge. If the pressure does not drop after cleaning, the cartridge can continue in service for many cycles.

What warranty does Solberg provide for this filter cartridge?

Solberg offers a one‑year limited warranty covering material defects and workmanship. The warranty does not cover damage caused by improper installation, misuse, or cleaning with unsuitable chemicals.

Is the cartridge suitable for hazardous material filtration?

The polyester media is effective for non‑reactive particulate filtration, but it is not designed for chemical absorption or corrosive gases. For hazardous or chemically aggressive environments, select a cartridge specifically rated for those substances.
