KOCH

KOCH Filter is a US-based manufacturer of air filtration products, with a history dating back to 1940. The company produces a range of filter types for commercial and industrial HVAC systems, including pleated filters, rigid cell filters, and minipleat (V-bank) filters. KOCH filters are commonly specified where particulate removal efficiency is defined by MERV ratings, and where frame construction and media material must match the mechanical and chemical conditions of the air handling unit. 3G Electric supplies KOCH air filters globally, with stock covering MERV 8 pleated filters, MERV 11 rigid cell filters, and MERV 14 minipleat filters in various standard face and depth dimensions. The product line is organized around three primary construction families. Pleated filters use synthetic media in a beverage board frame, available in MERV 8 ratings and depths of 2 or 4 inches. These are general-use filters for capturing dust, pollen, and mold spores in commercial HVAC systems. Rigid cell filters use fiberglass media in a galvanized steel frame, rated MERV 11, and are built for applications requiring a self-supporting filter that maintains its shape under high airflow. Minipleat filters, also called V-bank filters, use fiberglass media with either a plastic or galvanized steel frame, rated MERV 14, and are used for high-efficiency particulate removal in industrial air filtration. Across these families, KOCH filters are specified by nominal dimensions (face size and depth), media material, frame or header material, and MERV rating. Header configuration—single-header, no header, or gasket location—is a key selection variable because it determines compatibility with holding frames and track systems in the air handler. 3G Electric maintains inventory of KOCH filters across these configurations, including part numbers such as 110-734-001, 111-501-103, 120-720-001, 120-730-001, 102-701-031, 102-700-017, 102-700-022, and 102-701-017. For plant engineers and maintenance managers, the practical selection criteria are the target MERV rating, the physical dimensions of the filter rack, the required frame material for the operating environment, and whether a header or gasket is needed for sealing. 3G Electric provides specification-level data for each KOCH filter, including manufacturer part number, media material, frame material, gasket location, and nominal dimensions, so that buyers can match replacements to existing filter schedules without ambiguity. The KOCH line is used in commercial buildings, industrial process areas, and institutional facilities where air filtration is part of a maintenance program. Because 3G Electric ships globally, the KOCH filters listed in the catalog are available to buyers outside the United States as well as within it. The catalog includes both standard nominal sizes and less common dimensions, such as 25 x 16 x 2 inches and 12 x 24 x 12 inches, which helps maintenance teams source replacements for non-standard filter racks. For procurement specialists, the key advantage of the KOCH line through 3G Electric is the availability of detailed technical attributes—MERV rating, media type, frame type, header configuration, and exact dimensions—presented alongside the manufacturer part number, which reduces the risk of ordering an incompatible filter. The filters are supplied as individual units, and 3G Electric can provide quotes based on the specific part numbers and quantities required.

Frequently asked questions

Common questions about KOCH from 3G Electric.

What MERV ratings are available in the KOCH air filter line?

KOCH air filters supplied by 3G Electric include MERV 8 pleated filters, MERV 11 rigid cell filters, and MERV 14 minipleat (V-bank) filters. MERV 8 pleated filters use synthetic media in a beverage board frame and are intended for general HVAC particulate capture. MERV 11 rigid cell filters use fiberglass media in a galvanized steel frame and are self-supporting for higher-velocity applications. MERV 14 minipleat filters use fiberglass media with either a plastic or galvanized steel frame and are specified for high-efficiency particulate removal. The MERV rating is determined by the filter's tested performance under ASHRAE 52.2, and selection should be based on the target efficiency and the pressure drop the system can accommodate.

What is the difference between KOCH minipleat and rigid cell filters?

KOCH minipleat filters, also called V-bank filters, use closely spaced pleats of fiberglass media arranged in a V configuration to increase media area within a given face size. They are available in MERV 14 and use either a plastic or galvanized steel frame, with single-header or no-header options. KOCH rigid cell filters use fiberglass media in a galvanized steel frame and are rated MERV 11. Rigid cell construction provides a self-supporting filter that resists deformation under high airflow, while minipleat construction offers higher media area and efficiency in a similar footprint. The choice depends on the required MERV rating, the available depth, and the holding frame or track system in the air handler.

How do I select the correct KOCH filter for my HVAC system?

Selection requires four pieces of information: the nominal face dimensions and depth of the existing filter, the required MERV rating, the frame or header material compatible with the filter rack, and whether a gasket or header is needed for sealing. KOCH filters are specified by nominal size (for example, 24 x 24 x 12 inches), media material (fiberglass or synthetic), frame material (galvanized steel, plastic, or beverage board), and header configuration (single-header, no header, or gasket location). 3G Electric lists these attributes for each KOCH part number, so buyers can match replacements to the existing filter schedule. If the filter rack uses a track system, confirm the header type before ordering.

Are KOCH MERV 14 minipleat filters available with different frame materials?

Yes. KOCH MERV 14 minipleat filters are available with either a plastic frame or a galvanized steel frame. For example, part number 111-501-103 uses a plastic frame with a single header, while part number 120-720-001 uses a galvanized steel frame with a single header. Part number 120-730-001 uses a galvanized steel frame with no header. The frame material affects structural rigidity, weight, and compatibility with certain holding frames. Plastic frames are typically used where corrosion resistance or lighter weight is preferred, while galvanized steel frames are used where higher mechanical strength is required. Both configurations use fiberglass media and are rated MERV 14.

What sizes of KOCH pleated air filters does 3G Electric supply?

3G Electric supplies KOCH MERV 8 pleated air filters in several nominal sizes, including 24 x 24 x 4 inches (part number 102-701-031), 24 x 16 x 2 inches (part number 102-700-017), 24 x 24 x 2 inches (part number 102-700-022), and 25 x 16 x 2 inches (part number 102-701-017). All use synthetic media and a beverage board frame. These are general-use filters for commercial and industrial HVAC applications, capturing dust, pollen, and mold spores. Because nominal sizes vary by filter rack, buyers should verify the actual face dimensions and depth before ordering. 3G Electric lists the exact nominal dimensions for each KOCH part number in the catalog.

Can KOCH air filters be used in industrial air filtration applications?

Yes. KOCH air filters are used in both commercial HVAC and industrial air filtration. The MERV 14 minipleat filters, such as part numbers 111-501-103, 120-720-001, and 120-730-001, are specified for industrial air filtration where higher particulate removal efficiency is required. The MERV 11 rigid cell filter, part number 110-734-001, is used in commercial and industrial HVAC systems that need a self-supporting filter. MERV 8 pleated filters are used for general air filtration in commercial and industrial settings. The appropriate filter depends on the contaminant load, the required efficiency, and the mechanical constraints of the air handling system.
