SprayStopTM Synthetic Overspray Medias Koch offers a complete range of overspray medias for the collection of all types of paint overspray and industrial coating materials. Four types of polyester overspray media are available; SprayStopTM S, SprayStopTM SHC, SprayStopTM 550, and SprayStopTM STK. SprayStopTM S and SHC offer superior efficiency and holding capacity for high volume thermo-set coatings. SprayStopTM 550 and STK are designed to capture air-dry coating such as aerospace primers, and they provide excellent pre-filtration in spray-to-waste powder coat operations. All four medias are constructed with a specialized fiber blend available only from Koch Filter Corporation which was developed specifically for paint overspray applications. SprayStop media is available in Bulk Rolls, Blankets, and Pads to meet any booth size requirement. CONSULT PRODUCT BULLETIN NO. 798-1, 798-2, 798-4, 798-7.

SprayStopTM Expanded Paper Overspray Media This media is widely used in a variety of overspray applications. SprayStopTM 3000 consists of nine layers of slit and expanded kraft paper, while SprayStopTM 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.

SprayStopTM System 2 SprayStopTM System 2 is a two-stage overspray system composed of SprayStopTM STK or 550 in the first stage, with a high efficiency SprayStopTM 650 bag filter as the final filter. System 2 complies with EPA Test Method 319 Guidelines for two-state systems, and is designed specifically for use in aerospace applications where anticorrosive primers and other chromate-laden coatings are present. CONSULT PRODUCT BULLETIN NO. 798-9

SprayStopTM System 3 SprayStopTM System 3 is a three-stage overspray system composed of SprayStopTM S or SHC overspray media in the upstream stage, an MG300 or MG550 Panel as the second stage, and a high efficiency Multi-Sak 9S 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.

SprayCleanTM Duo-Pak 550 and SprayCleanTM 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 tackified overspray collectors in air-dry or powdered paint applications. Self-seal and header models are available. CONSULT PRODUCT BULLETIN NO. 798-5,6

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. CONSULT PRODUCT BULLETIN NO.

SprayCleanTM KDF 600 Diffusion Media KDF 600 will improve First Pass Capability and reduce defects in downdraft spraybooths 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. CONSULT PRODUCT BULLETIN NO. PB-798-3

High Efficiency Final Filters Koch manufacturers several models of high efficiency filters for use as secondary of 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%, 95% efficiency range. This wide range of alternatives ensures that Koch can be a single-source supplier for any pain filtration requirement. CONSULT PRODUCT BULLETIN NO. K996, 288B, 288C, 787A

Dust Collection Cartridges Koch Dust Collection Cartridges are used worldwide in powder coating, grinding, and spray-to-waste operations. By back-pulsing air through the filters, Koch DC Cartridges are self-cleaning, and can greatly reduce operational costs where high concentrations of contaminant are gathered.
