ULVAC UPD-6 & DTC-41 Diaphragm Vacuum Pumps

ULVAC UPD-6 Diaphragm Vacuum Pump

High-Capacity Japanese Engineering for Industrial Applications

The ULVAC UPD-6 is an Ai exclusive, compact, lightweight diaphragm vacuum pump manufactured and imported directly from Japan, delivering high-capacity performance through reciprocating movement of rubber diaphragms. This full chemical-resistant 2-head pump generates 6 CFM pumping rate with ultimate vacuum capability of 6 torr, making it ideal for demanding industrial applications including moisture and solvent evaporation, vacuum chucks, wafer and tip handling devices, printing equipment, automatic packing machines, and semiconductor manufacturing. The oil-free design eliminates maintenance costs associated with oil changes while preventing cross-contamination, crucial for clean-room environments and sensitive processes. UL/CSA listed for North American compliance, the UPD-6 operates on 220V 50/60Hz single phase power (400 watts, 5.6 amp rated current) with KF25 flange connections for standardized vacuum system integration.

Reliable Performance with Low Noise Operation

Measuring 400×178×330mm and weighing just 26 kg, the UPD-6 combines powerful performance with portability for flexible laboratory and industrial placement. The pump operates quietly at 68 dBA at atmospheric pressure, reducing to 62 dBA at ultimate pressure—important for laboratory environments where noise reduction is valued. Designed for continuous operation in working environments from 0°C to 40°C, this robust system provides dependable service across diverse applications including vacuum tweezers, medical appliances, optical equipment, and semiconductor processing. Available exclusively through Ai as the official ULVAC dealer, the UPD-6 comes with comprehensive one-year warranty and full technical support from ULVAC, ensuring long-term reliability for critical vacuum applications.

ULVAC UPD-6 Features:

  • Reliable Protection: Covered by a 1-Year Warranty for peace of mind.
  • High Pumping Capacity: 6 CFM throughput for demanding industrial and laboratory applications.
  • Deep Vacuum Performance: Achieves 6 torr ultimate vacuum level for effective process control.
  • Full Chemical Resistance: 2-head rubber diaphragm design handles corrosive gases and solvents.
  • UL/CSA Certified: Listed compliance ensures safety for North American installations.
  • KF25 Flange Connections: Standardized fittings for seamless vacuum system integration.
  • Quiet Operation: 68 dBA at atmosphere, 62 dBA at ultimate pressure for laboratory environments.
  • Compact Japanese Engineering: 400×178×330mm footprint, 26 kg weight for portability.
  • Wide Application Range: Ideal for semiconductor, printing, medical, and optical industries.
  • Oil-Free Technology: Eliminates maintenance costs and contamination risks.

ULVAC DTC-41 Diaphragm Vacuum Pump

Two-Stage PTFE Excellence for Corrosive Applications

Manufactured and imported directly from Japan, the ULVAC DTC-41 features two-stage PTFE diaphragms with integral forced-air cooling, making it ideal for pumping corrosive gases and organic solvents where only PTFE components contact the vacuum environment. This compact, portable oil-free pump delivers 1.62 CFM pumping rate with ultimate vacuum capability of 7.5 torr (10 mbar), achieving impressive performance such as pumping down a 0.9 cubic foot oven in just 6 minutes. TUV certified to UL and CSA standards, the DTC-41 operates on 220V or 230V 50/60Hz single phase power (0.13 HP, 100 watts, 1.1 amp full load current) with convenient 3/8" hose barb connections. The chemical-resistant design eliminates costly oil changes and cross-contamination concerns while providing reliable service for rotary evaporators, evaporating systems, vacuum concentrators, filtration, drying systems, medical and pharmaceutical equipment, centrifuges, and laser-gas circulation applications.

Portable Precision with Superior Chemical Protection

Exceptionally compact at 330×140×220mm and weighing only 10.5 kg, the DTC-41 is designed for maximum portability without compromising performance. The integral forced-air cooling system ensures consistent operation even during extended use, while ultra-quiet operation at just 53 dB(A) makes it ideal for laboratory environments where noise is a concern. The pump's two-stage PTFE construction provides superior protection against aggressive chemicals, with all vacuum-exposed components manufactured from PTFE for uncompromising chemical resistance. Designed to back most hybrid turbo pumps and suitable for working environments from 32°F to 104°F (0°C to 40°C), the DTC-41 delivers reliable, maintenance-free performance. Available through Ai as the official ULVAC dealer, each pump includes complimentary three feet of 3/8" white premium food-grade silicone vacuum tubing ($19.99 value) and comes with one-year warranty and full technical support from ULVAC.

ULVAC DTC-41 Features:

  • Reliable Protection: Covered by a 1-Year Warranty for peace of mind.
  • Two-Stage PTFE Diaphragms: Complete PTFE vacuum path for maximum chemical resistance to corrosive gases.
  • Integral Forced-Air Cooling: Maintains optimal operating temperature during extended use.
  • Compact and Portable: Ultra-lightweight 10.5 kg design with 330×140×220mm footprint.
  • Energy Efficient: Low power consumption at 100 watts (0.13 HP) reduces operational costs.
  • Ultra-Quiet Operation: 53 dB(A) noise level ideal for laboratory environments.
  • Reliable Vacuum Performance: 1.62 CFM with 7.5 torr ultimate vacuum, pumps 0.9 cu ft in 6 minutes.
  • TUV Certified: Meets UL and CSA standards for safety compliance.
  • Versatile Applications: Ideal for rotary evaporation, filtration, drying, medical equipment, and centrifuges.
  • Complete Package: Includes premium food-grade silicone tubing and one-year warranty with full ULVAC support.
