Pfannenberg Highlights NEMA Type 3R/4/4X Rainhoods

Certified Protection for Applications in Outdoor & Harsh Environments.

Lancaster, NY - Pfannenberg, Inc., a leading global manufacturer of thermal management and signaling technologies, highlights its NEMA Type 3R/4/4x Filterfan® Rainhoods for protecting applications from outdoor & harsh environments like rain, water spray, snow, or fluids. Offering multi-dam seal technology, the high-compression, closed cell gasket ensures a proper NEMA Type/IP rating seal to the enclosure. Its unique mounting system also offers certified protection when used with Pfannenberg Filterfans® and exhaust filters. Pfannenberg tests the Filterfan® with and without the fan running during certification, ensuring the highest quality and reliability.


Pfannenberg Rainhoods deliver maximized airflow capabilities and superior overspray protection. The direct spray barrier and high air-flow baffle shield overspray from entering the cabinet while minimizing airflow loss. The toolless design allows for easy removal of the rainhood for accessible maintenance and filter mat replacement. Pfannenberg also offers tamper-proof options. Installation is also easy, as the mounting bracket can painlessly be installed to the enclosure around the existing cutout.

Options include painted galvanized steel, stainless steel, and FDA compliant food and beverage grade versions, ensuring hoods look sleek and function well. All options of the Pfannenberg Rainhood share the same reliable rugged steel construction. In addition to the standard painted and stainless-steel designs, Pfannenberg also offers a specialty 4X stainless steel rainhood to meet the FDA-compatible requirements found in food and beverage manufacturing facilities.

The ERT150 - Dorner’s Next Evolution of Edge Roller Technology Conveyors

The ERT150 - Dorner's Next Evolution of Edge Roller Technology Conveyors

The next evolution in Dorner's Edge Roller Technology conveyor platform, the ERT®150, is ideal for small and light-load assembly automation, as well as medical and medical-device assembly application. The ERT platform is the only pallet conveyor of its kind available with an ISO Standard Class 4 rating for cleanroom applications. Earning the ISO Standard 14644-1 Class 4 rating means Dorner's ERT150 will conform and not contribute to the contamination of cleanrooms to those standards. As implied by its name, the ERT150 (Edge Roller Technology) uses rollers to move pallets through the conveyor smoothly with no friction (a byproduct often seen in belt-driven platforms). The conveyor's open design eliminates concerns of small parts or screws dropping into rollers and causing conveyor damage or jamming. The ERT150 is suited to operate in cleanroom environments requiring a pallet handling conveyor. It is capable of zoning for no or low-back pressure accumulation and is ideal for automation assembly applications within industries including medical devices, electronics, consumer goods among others.
