Miniature Diaphragm Pumps (air/gas) BTC SeriesUp to 6 LPM Free Flow Miniature Pumps Typical Applications • Gas Analysis • Anesthesia Monitors • CO2 Monitors • Patient Monitoring • Wound Therapy • Urinalysis • Medical/Training Mannequin BTC Miniature Diaphragm Pumps are a series of brush and brushless DC motor driven pumps, which are tailored to meet specific application performance requirements. An innovative compact design incorporates leading edge technologies that allow them to operate more efficiently than existing pump designs. BTC Pumps offer multiple component configurations allowing them to be used for either vacuum, pressure, or alternating vacuum and pressure operations. BTC series is ideal for a wide range of pressures and low noise applications. Features • Innovative and efficient engineering designs enable the BTC Series to push the performance envelope in a lightweight, compact size. • Using our proprietary advanced diaphragm elastomer and superior brushless motor design sets the highest benchmark for service-free operation that exceeds 10,000 hours. • Incorporating the lightweight EZ Mount Accessory facilitates simple system assembly while dampening vibration and reducing noise levels. • RoHS compliant. ~ RoHS Product Specifications Physical Properties Operating Environment1 : 41 to 122°F (5 to 50°C) Storage Environment : -4 to 212°F (-20 to 100°C) Media: Air, Argon, Helium, Nitrogen, Oxygen, and other non-reacting gases Humidity: 0% - 80% Relative Humidity Noise Level2 : As low as 45 dB @ 12 in (30 cm) Muffler recommended for additional noise reduction (see accessories) Pump Assembly Rated Life3 : PMDC Iron Core Brush - 3,000 hrs Brushless Slotted - 10,000 hrs Brushless Slotless - 10,000 hrs Weight: 6.5 oz.
