Working in harsh environments can expose employees to dangerous airborne particulates, such as lead, mold or asbestos. To combat this serious health issue, Casella USA today introduced its TUFF™ line of personal air sampling pumps featured an over-molding sealed case that protects internal electronics from damaging moisture, extreme temperatures, solvents, and impact. Offering a wide flow range from 5 ml/min to 4.5 l/min, the three pumps that comprise the Casella TUFF line are ideally suited to a wide range of occupational health applications from simple abatement sampling, to more specialized industrial hygiene monitoring of dusts, fumes and vapors. All pumps incorporate a proven efficient double-acting diaphragm pump mechanism with precise digital control. This offers the user excellent real time flow control and stability across a wide range of sampling media. Navigation is guided by an intuitive user interface displaying real time flow, sampled volume and run duration, as well as a battery “fuel gauge” and an alarm for flow or battery fault conditions. Industrial hygiene professionals can select the TUFF pump they need from either the standard model, the TUFF Plus, or the high-end TUFF Pro. This choice easily enables them to customize a pump for specific requirements by a combination of firmware programmed into the main pump body and then adding either a 1.7 or 2.7 Ah battery pack, a 3 or 4.5 I/min maximum flow rate capacity, and battery cell charger to make a fully working model. Each of the pumps feature 4.8V NiMH rechargeable battery cells with operational run times of five hours, making them the perfect choice when there is no electrical power within the containment area.Rounding out the pump introduction is a full line of Casella accessories including sampling heats, bubblers, filter media, and sorbent tubes, along with rotameters and calibrators to calibrate TUFF pumps to ensure compliance to sampling methodologies. Casella TUFF air sampling pumps meet EN1232 and NIOSH 0600 requirements for personalized sampling pumps in workplace environments, and are pending approval for IEC Ex, ATEX and UL listing as being intrinsically safe. • Flow Range: 5 ml /min* to 4.5L /min • (3L /min on Tuff 3 variant) • Flow Control Accuracy: Control typical < +/-3% at calibrated point • Inlet Pulsation Ratio: <10% @ 2L /min • Runs Stored: 100 (Pro Versions Only) • Display: 100 x 32 Graphics LCD • Typical Charge Time: < 3hrs from discharge / 3 way - 5hrs • Size mm: 133 x 87 x 47mm • Weight gm: 480g • Service Interval: Recommended 2500 hrs • IP Ratings: Gasket Sealed Case IP54 • Intrinsic Safety Approvals: EEx ib IIC T3 Atex II I G (Pending) • Environmental: • In storage: Temperature: -10 to +50ºC • Humidity: 30-95% RH (non condensing) • In operation: Temperature: 0 to 45ºC • Humidity: 30-95% RH (non condensing) • Operation Duration: @2.0L /min via 25mm GFA flter: • >30hrs 2.7Ah / >20hrs 1.7Ah
