Thumbnail Filmstrip of TE-5070 110V Brush Style Motor Assembly for VFC Systems Images
The TE-5070 is a 110-volt brush style motor assembly specifically designed for Volumetric Flow Controlled (VFC) air sampling systems. This complete blower motor assembly delivers 1.0 HP of power for maintaining consistent flow rates in EPA-compliant ambient air quality monitoring applications. The motor features double ball bearing construction with through-flow discharge design for reliable, continuous operation.
Motor Performance
The TE-5070 operates on single phase power with earth ground at 110V/60Hz, delivering consistent performance with 20 startup amps and 8 running amps. Designed for continuous operation in ambient temperatures from -30°C to +50°C and relative humidity from 0-100%, with altitude capability to 10,000 feet above sea level. The motor provides flow rates of 42-45 CFM continuous for TSP sampling applications.
Key Specifications
- Power: 1.0 HP, 110V/60Hz single phase
- Current Draw: 20 amps startup, 8 amps running
- Flow Rate: 42-45 CFM continuous
- Construction: Double ball bearing, through-flow discharge
- Operating Temperature: -30°C to +50°C
- Altitude Rating: Up to 10,000 feet
System Compatibility
The TE-5070 is the standard VFC blower motor assembly for Tisch Environmental's volumetric flow controlled air sampling systems, including the TE-5170-V sampler. The assembly includes the TE-115923 motor, aluminum housing (TE-5070-2), motor cushion, spacer rings, power cord, and pressure tap tubing. Works with volumetric flow controller (TE-10557TSP) and 8" x 10" filter holders for EPA-compliant TSP monitoring per 40 CFR Part 50, Appendix B.
Replacement Parts & Maintenance
Motor brushes (TE-33392) should be inspected regularly and replaced as needed to maintain optimal performance. Other serviceable components include the motor housing (TE-5070-2), hold-down ring (TE-5070-3), and motor cushion (TE-5005-4). For users requiring 220V operation, the TE-5070X provides equivalent performance at 220V/50Hz.
Applications
Designed for EPA-compliant Total Suspended Particulate (TSP) monitoring that meets the new EPA Lower Lead (Pb) Standard of 0.5µg/m³. Suitable for ambient air quality monitoring stations, environmental compliance testing, and research applications requiring consistent volumetric flow control. The VFC design automatically compensates for filter loading to maintain constant volumetric flow throughout the sampling period.
