SprayStop™ 3000 consists of nine layers of slit and expanded kraft paper, while SprayStop™ 3200 offers the added benefit of a polyester backing downstream for increased efficiency. Several additional expanded paper medias are available for special applications. SprayStop media is available in Bulk Rolls, Blankets, and Pads to meet any booth size requirement.
SprayStop™ FG Fiberglass Overspray Media
SprayStop™ FG media is composed of multiple layers of glass fiber and has been a popular media for various types of paint overspray applications for many years, especially in applications where initial purchase price is of utmost concern. Economical SprayStop fiberglass is available in Bulk Rolls, Blankets, and Pads to meet any booth size requirement.
SprayStop™ Duo-Pak S and Duo-Pak 650
Koch offers two unique extended surface bag-type filters for use in paint overspray systems, SprayStop™ Duo-Pak S is the filter of choice in the collection of thermo-reactive coatings when efficieny and service life are necessary.
SprayStop™ Duo-Pak 650 is designed to meet MACT Standards for all coatings materials, including aerospace primers and other hard-to-capture overspray contaminants. SprayStop Duo-Pak 650 has been tested and verified according to EPA Test Method 319, and meets NESHAP requirements for aerospace applications where two-stage filtration is permitted.
SprayStop™ System 2
SprayStop™ System 2 is a two-stage overspray system, composed of SprayStop™ STK or 550 in the first stage, with a high efficiency SprayStop™ 650 bag filter as the final filter, System 2 complies with EPA Test Method 319 Guidelines for two-stage systems, and is designed specifically for use in aerospace applications where anticorrosive primers and other chromate-laden coatings are present.
SprayStop™ System 3
SprayStop™ System 3 is a three-stage overspray system composed of SprayStop™ S or SHC overspray media in the upstream stage, an MG300 or MG550 Panel as the second stage, and a high efficiency Multi-Sak 95 final filter as the third stage (standard or self-seal). System 3 complies with
EPA Test Method 319 Guidelines for three-stage systems, and is designed for optimum performance and service life in aerospace coatings operations where high levels of chromates are common.
SprayClean™ Filters for Make-Up Air Filtration
SprayClean™ Duo-Pak 550 and SprayClean™ Duo-Pak 40
Koch Duo-Pak 550 (three-ply) and Duo-Pak 40 (two-ply) filters are extended surface pocket filters designed for maximum service life and superior efficiency for capturing particulate larger than 5 microns in diameter. Both models may be used as Pre-Filters to extend the life of high efficiency filters, or they may be used as tactified overspray collectors in air-dry or powdered paint applications. Self-seal and header models are available.
Pre-Filter Options
To protect and extend the life of costly high efficiency filters. Koch offers Multi-Pleat Extended Surface Filters and Maxi-Grid 300 and 550 Internally-Supported Panels. The Multi-Pleat, one of the world’s most widely used pre-filters, is available in efficiencies ranging from 20-40% and is offered in many models, including a High Temperature version for paint curing ovens.
Maxi-Grid Panels are internally-supported three-ply filters constructed with graduated density polyester media.
Equipped with a self-sealing edge to eliminate air and dirt bypass in the paint booth, Maxi-Grid Filters are easy to install with no clips or holding devices required.
SprayStop™ KDF 600 Diffusion Media
KDF 600 will improve First Pass Capability and reduce defects in downdraft spray booths while providing contaminant-free, laminar airflow with an efficiency level of 99.5%+ on particles above 4 microns. The progressive density fiber matrix creates superior fractional efficiency and prevents the migration of contaminants that cause surface blemishes. Available in blankets, cut pads, or cross-wire panels to fit any downdraft application, or engineered specification.
High Efficiency Final Filters
Koch manufactures several models of high efficiency filters for use as secondary or final stage filtration in the make-up air section of a paint operation. DuraMAX Minipleat Filters, Multi-Sak S, Multi-Flo Rigid Filters, Multi-Cell High Temperature Filters, and several other choices give the customer multiple options in the 65%, 85%, and 95% efficiency range.
