Sub-high Efficiency Air Filter Product Introduction

Sub-high efficiency air filters are primarily designed to capture particulate dust and various suspended particles smaller than 0.5um, serving as the final filtration stage in various filtration systems. Crafted with ultra-fine fiberglass paper as the filtering media, these filters employ folded cardboard, aluminum foil, and other materials as partition plates, sealed with innovative polyurethane sealant. The external frame is constructed from galvanized steel plates, stainless steel plates, or aluminum alloy profiles. Additionally, there are three types of high-efficiency filters: the ultra-high-efficiency filter, capable of achieving 99.9995% purification; the antibacterial partitionless high-efficiency air filter, with antibacterial properties to prevent bacteria from entering clean workshops; and the sub-high-efficiency filter, known for its affordable price and previous widespread use in less demanding clean spaces. Both high-efficiency and ultra-high-efficiency filters are utilized at the end of cleanroom systems and can be classified by their structural forms into partitioned high-efficiency filters, partitionless high-efficiency filters, high-volume high-efficiency filters, and ultra-high-efficiency filters.

Technical Parameters

Product Introduction: High-efficiency air filters specialize in capturing particulate dust and suspended particles smaller than 0.5um, functioning as the final filtration element in diverse filtration systems. They utilize ultra-fine fiberglass paper as the filtering media, with folded cardboard, aluminum foil, and other materials serving as partition plates. These filters are sealed with modern polyurethane sealant and enclosed in a frame made of galvanized steel, stainless steel, or aluminum alloy.

Performance Features

Partitioned Design: The corrugated partition design effectively maintains the spacing between pleats.

Optimal Filter Material Utilization: Maximizes the use of filter media under minimal resistance.

Innovative Pleat Design: The filter material is double-folded at 180 degrees, creating a wedge-shaped pleat layer with two creases during bending. This design forms a wedge-shaped box pleat at the end of the partition, which helps prevent filter material damage.

Corrosion Resistance: In corrosive environments, vinyl-coated partitions can be used, achieving a 99.9999% efficiency in capturing particles as small as 0.12μm.
