With a flow range from 5 ml/min to 4.5 l/min, Casella TUFF pumps are ideal for a wide range of occupational health and safety applications from simple abatement sampling to more specialized industrial hygiene monitoring of dusts, fumes and gases. All pumps incorporate a proven efficient double-acting diaphragm mechanism with precise digital control. This gives the user excellent real time flow control and stability across a wide range of sampling media. Pump operation is guided by an intuitive user interface displaying real time flow, sampled volume with run duration, as well as a simple battery "fuel gauge" and alarm for flow or battery fault conditions. Intrinsically Safe (IS) models are available for use in hazardous locations.
Safety and health professionals can specify the features they need by selecting the standard model, the TUFF Plus, or TUFF Pro. By choosing a 1.7 or 2.7 Ah battery pack, 3 or 4.5 L/min maximum flow rate capacity the user can optimize performance and price to meet their exact needs. Every TUFF pump uses detachable and field-swappable NiMH battery packs ensuring maximum uptime. Typical run times of more than 30 hours (depending on media and flow rate) make them the perfect choice for longer sampling periods. Casella TUFF air sampling pumps meet applicable NIOSH and EN requirements for personal sampling pumps.
Casella offers a full line of accessories including sampling heads, impingers, filter media, and sorbent tubes, plus rotameters and calibrators for flow verification ensuring compliance with accepted sampling methodologies.
