As one of Taiwan's leading manufacturers of three-lobe, positive displacement roots blowers, vacuum pumps, bubble diffusers and soundproof enclosures, we have been steadily gaining ground across much of Asia. Our ISO and CE certified OEM service and brand have reached across to major engineers and distributors throughout Japan, China, Korea, all of South-East Asia, the Middle-East (Saudi Arabia, UAE) as well as Australia, New-Zealand, Denmark and Poland. We are now in the process of extending out towards India, Indonesia, more of the Middle East, in addition to the rest of Europe, North and South America, Russia and Africa.

General Features
L High quality standards (3D machine).
L Technical customization (size, pressure, design, pump accessories)
L CNC machinery grinding.
L Manual assembly.
L Fewer vibrations transmitted through the lobe, for longer-lasting shafts, gears and bearings.
L Lubricated with high grade oil, proven to be a much better alternative to grease.
L Improvement in air performance ratios: Wider air, pressure and vacuum range, more stable flow, fewer pressure variations.
L Quieter by 5 dB.

Performance
Capacity: 0.5-320 cubic meters per minute
Pressure: 1000-10000 mmAq (water cooling option available for above 8000mmAq)
Rotation: 900-2500 rpm

All Applications
L Pneumatic conveying
L Waste water treatment plants
L Electroplating tanks
L Printing
L Activated sludge systems.
L Drying systems
L Absorption transporter (for high standards of hygiene)
L Filters
L Hospitals and dentistry

Soundproof Enclosure
If you need a quieter environment in the vicinity of your pumping system, we will design a special soundproofing enclosure suited to the blower that you wish to order (Original Design Manufacturer). These are built to reduce noise by up to 5 to 10dB depending on the performance ratio.

Ltd-080 Rubber Disk Diffuser
4/8"faucet
Easy to install.
Long-lasting
Higher oxygen dissolution rate
Corrosion resistance.
Prevents backflow without clogging.
4/8"-thread, 3/8"-Air inlet
Diameter: 80mm
Height: 40mm
Ventilation Volume: 0.08~0.10m3/min
Ltd-144 Disk Diffuser
L Pipeline caliber for connection:
PT1B thread.

L Limits pressure losses:
The flexible valve enables precise adjustment of the pressure discharge force with the use of an air volume gauge, leading to fewer pressure losses.
L Corrosion resistance, constructed with a state-of-the-art ABS compound, boasting outstanding temperature resistance.
L Long-lasting (three times the life-span of ordinary rubber)
L Oil and corrosion resistant valve.
L Fully-closed against backflow

Should the pump be stopped, a specially constructed valve is designated to provide a complete seal between the cut-out air flow from underneath and the water pressure above. This naturally prevents any undesired backflow of water into the apparatus.
