Nanofiber Pleated Filter Cartridge
Patent-pending nanofiber media provide high-performance emissions control for the most challenging industrial fume and dust applications. The cartridge filter is ideally suited for applications such as material handling, mixing and blending, packaging and bagging stations, and paint booth and powder coating. The high-efficiency filter utilizes sub-micron-diameter nanofibers bonded to a substrate of filter media. The nanofilter technology provides optimized airflow and reduced differential pressure, reduced cleaning cycles, and longer service life, leading to less-frequent changeouts. It eliminates blinding problems, reduces emissions, and is easy to install and maintain.

Filtration and Containment System
The Absolut filtration and containment system contains and removes active-compound and toxic-product dust during industrial and pharmaceutical production. It can filter extremely fine dust particles and aerosols, bringing pharmaceutical processing contamination levels down well below the most stringent occupational exposure limit (OEL). The system provides an extremely low airborne dust level during handling via the use of two HEPA filters that allow cleaned air to be reintroduced back into the production area with no impact on room-to-hallway air balancing.

Single-Cartridge Dust Collector
The Gold Series GS-Mini single-cartridge dust collector provides high performance for sub-500-cfm applications. It may be used as a dedicated collector for one process machine or as a bin vent on a silo. Its HemiPleat filter cartridge features an open-pleat medium that provides up to twice the service life at half the delta P of standard cartridges. The collector comes with a filter, spark-proof fan, manual pulse system, and pressure-drop gauge. A variety of options are offered for specialized applications.

Tube Line Cleaner
The tube line cleaner (TLC) solves the problem of inaccurate pressure data and is suitable for a wide range of applications where pneumatic tubing must remain clear of blockage. It is typically installed in applications that include pressure sensor lines that are used with demand controllers in dust collectors. Benefits include automatic line clearing, effective filter differential-pressure measurement, continuous reliable use of pressure sensors in the dust collector, minimal dust ingress into equipment mounted to the lines, and reduced equipment damage.

Cartridge Collector
This cartridge collector is offered for airflows up to 3000 CFM in powder-processing applications. The company guarantees at least a three-year cartridge life using its heavy-duty LP-series cartridge collector, which comes with bottom drawers or a 55-
gallon drum. The fan can be top or side mounted. This cartridge series uses nozzle technology for superior filter cleaning and includes a unique spring locking assembly that ensures that filter gaskets will not leak.

All-ePTFE Filter Bag
Company has added an all-ePTFE laminate choice to its Gore high-durability filter bag family. The all-expanded polytetrafluoroethylene filter bag is designed to provide increased performance in aggressive chemical environments. In addition to resisting chemical attack, the ePTFE membrane and ePTFE backer also ensure long-term performance in extremely hot and humid environments. The new filter bag provides longer operating life, less downtime, and greater recoverability than partial or non-ePTFE filters, while still improving product collection. It can be used in elevated humidity and temperatures reaching 500°F.

Cartridge and Baghouse Filters
Dura-Life and Ultra-Web filters for cartridge and baghouse collectors are available for most popular brands of dust collectors and are ready to ship in 24 to 48 hours. Proven to filter even submicron dust at high MERV 13 efficiency levels, Ultra-Web lasts up to twice as long as commodity filters and reduces emissions by 40 percent or more. Dura-Life bags provide twice the bag life, 30 percent fewer emissions, and lower maintenance costs than other filters. They are 99.9 percent efficient and save energy.

Downward-Flow Dust Collector
The SFC downward-flow dust collector uses a patented pulse-blast system to clean the full length of cartridge filters. The system uses an optimized “diverging isothermal flow” nozzle and venturi to pulse air at a precisely calculated distance through an unobstructed airway. The result is increased pulse cleaning energy, lower pressure drop, and longer cartridge life.

Flexible Hose
Ahplus flexible hose has been designed for durability through reinforced construction. A replacement for older polyester neoprene hoses, it combines the best qualities of the company’s hoses with improved puncture, moisture, and tear resistance. It functions at higher temperature ranges and is UL94HB flame retardant. Strong and flexible, it is well suited for a wide range of oil mist, dust, smoke, fume, and airborne-particle collection applications. It withstands ozone, chemical, weather, UV, and aqueous, oil, or hydrocarbon-rich environments. Its distinct royal blue color enhances visibility in small shops and industrial settings.

Dustless Loading Spout
The Dustless Loading Spout is used for loading bulk material into trucks, railcars, barges, and ships, as well as for discharging material onto stockpiles. Benefits include fugitive-dust containment; three-cable winching for additional stability; and internal polyethylene, abrasion-resistant steel, urethane, or stainless-steel cones. Company offers complementary equipment such as loading spout positioners and integral dust collectors, as well as space-saver dust collector designs.

Retrofit Kit for Dust Collectors
This retrofit kit is ideal for dust collectors that are designed for oval-shaped cartridge filters. Requiring little assembly, the O Kit retrofit is based on two filter change-outs in an 18-hole collector. It results in savings of more than $1300, or close to $75 per hole. Based on two filter change-outs in a 128-hole collector, the savings are close to $10,000. The retrofit is simple and presents an economical alternative to premium-priced oval-shaped cartridges.

Modular Bin Vent Filter
The small modular design of the Modu-Kleen Series 669 bin vent filter makes it adaptable to almost any application where space is a concern. Each filter is totally independent and can be easily removed without having to gain entry to any kind of filter housing, simplifying maintenance and troubleshooting.
