Trusted Manufacturer of Ventilation and Air Cleaning Solutions

KTN VQX19 mini DC compressor: 2000-6000rpm adjustability lets the controller match output to load, holding wine cooler temperature more precisely while saving energy; 12V / 24V / 48V wide voltage, R134a with a 40cc oil charge, ≤48 noise, only 0.81 kg including oil, and two matched driver boards for plug-and-play integration.

KTN H13 HEPA 3-layer composite filter screen: the outer pre-filter traps hair and lint, the medical-grade H13 HEPA layer intercepts 99.97% of 0.3μm particles, and high-density activated carbon absorbs formaldehyde, cooking fumes and second-hand smoke — all with low wind resistance that preserves the purifier's air output, in multiple sizes with OEM customization available.

KTN smart silent air purifier: negative ion technology actively captures dust, pollen, pet dander, smoke and allergens, backed by HEPA and activated carbon filtration; smart sensors read air quality and adjust fan speed automatically, with app control and timers, and operation that is near-silent on low settings.

KTN Energy Recovery Ventilator (ERV): the dual-channel independent design eliminates cross-contamination between supply and exhaust; the total heat exchange core recovers energy while keeping humidity balanced, avoiding dryness or dampness; HEPA13 filtration captures 99.97% of 0.3μm particles and the activated carbon layer adsorbs chemical pollutants such as formaldehyde, with IoT remote monitoring and intelligent mode adjustment.

KTN VQX14 mini compressor: adjustable 2000-6000rpm speed to match cooling demand, DC 24V power for battery and DC systems, driver board and cable harness included so wiring is plug-and-play, and stable R134a cooling for easy mini fridge integration.

KTN VQX19 mini compressor: small footprint for easy integration into compact equipment, DC 24V power for battery and DC systems, stable R134a cooling; a matched driver board is included so wiring is plug-and-play, and the low-vibration design keeps equipment running quietly.

The VESTAR 7HP fixed-speed twin rotary AC compressor uses a symmetrical dual-rotor layout to cut vibration and noise, delivering the displacement commercial and central air-conditioning systems need; the proven fixed-speed structure keeps maintenance simple, and the compact steel shell integrates easily into unit assemblies.

The VESTAR vertical AC compressor uses a space-saving vertical structure, with a top lifting eye and side-mounted pipes that make assembly and service easier; its mounting feet and damping design keep operation smooth and quiet, backed by a corrosion-resistant steel shell.
