A layered PTFE air filter medium uses pre-collection and cover layers to limit clogging, deformation, and pressure loss in pleated units.

A two-stage filter pairs activated carbon with cyclodextrin binding media to capture smoke odors and pollutants beyond sorption saturation.

A layered PTFE filter medium uses tuned peel strength between membranes and supports to resist cleaning damage while preserving air permeability.

Microcreping laminated microporous membranes improves strength, stretch recovery, softness, and breathability for waterproof textiles.

Valve-controlled humid air channels adjust fuel cell humidification across operating conditions to prevent flooding, air starvation, and blower load.

A staged CO2 wash, PSA, and membrane process boosts helium recovery from CO2-rich gas while cutting power use and meeting pipeline limits.

Inner wall correction portions align the connection member before port contact, helping keep the dialysate collection port clean and leak-safe.

A permeable microcapsule fabric improves CO2 absorption from flue gas while lowering back pressure and extending capsule life.

A raised air inlet with a waterproof membrane filter equalizes pressure while blocking splashed water, reducing corrosion and insulation failure.

A rotating filter in the pump pressure chamber keeps washing liquor clear, prevents spray arm blockage, and avoids filter cake buildup.

A hydrophilic-oleophobic coating lets water pass through fabric while blocking oil, enabling durable, low-chemical oil-water separation.

Membrane separation with recycled CO2 and fractionation cuts energy use while recovering high-purity carbon dioxide from dilute gas streams.

A bimodal monocomponent nonwoven web enables a molded respirator to gain stiffness and filtration without extra layers or bicomponent fibers.
