T-101 by Allegro - High Volume Jarless Air Sampling Pump
T-101 by Allegro - High Volume Jarless Air Sampling Pump
The Allegro 9801-88 T-101 is a rugged, oil-free rotary vane sampling pump built for asbestos and industrial air quality sampling in compliance with OSHA and AHERA standards. It delivers a flow range of 0–30 LPM and operates on 115 VAC power, making it ideal for stationary high-volume air sampling applications including asbestos abatement monitoring, bulk material analysis, and environmental compliance testing. Its reliable oil-free design minimizes contamination risk and simplifies maintenance, providing dependable performance for regulated sampling programs.

What is the Allegro 9801-88 T-101 used for?
It's a high-volume area air sampling pump used for environmental and occupational health monitoring — asbestos (AHERA/OSHA), fibers, dust, mold spores, and other airborne particulates. Unlike personal sampling pumps worn by workers, the T-101 sits in a fixed location to characterize area air quality rather than individual exposure.
Area sampling pump vs. personal sampling pump — which do I need?
It depends on what you're measuring. An area pump like the T-101 samples the air in a defined space — useful for baseline surveys, clearance testing, and compliance monitoring of the work environment. A personal pump clips to a worker and samples the breathing zone, which is what OSHA requires for worker exposure limits. Some projects need both: area pumps to characterize the site and personal pumps for exposure documentation.
What flow range does it cover, and how is flow controlled?
The T-101 operates from 1–10 LPM with flow set via a front-panel dial. It uses a constant-flow motor to compensate for filter loading over time, which matters for long-duration area samples where the filter gradually restricts airflow. Verify actual flow with a calibrated rotameter or primary calibrator before and after sampling — especially for AHERA asbestos clearance testing.
Does this pump meet OSHA and AHERA requirements for air sampling?
Yes — the T-101 is accepted for AHERA asbestos abatement clearance sampling and OSHA industrial hygiene applications that call for area sampling. For AHERA clearance specifically, confirm your lab's accreditation (NVLAP) and follow the EPA 40 CFR Part 763 method. The pump's flow stability and the phase contrast microscopy analysis by a qualified lab are both required components for a defensible clearance result.
What's included in the Allegro T-101 rental kit?
The kit includes the T-101 pump, power cord, and inline filter holder. A rotameter for flow verification may be included — confirm at dispatch. Cassettes or filter media, chain-of-custody forms, and lab analysis are not included. For AHERA clearance work, coordinate your media and lab submission requirements before the rental period starts.
Why won't my pump hold the target flow rate during sampling?
The most common cause is filter overloading — as the cassette collects particulate, resistance builds and flow drops. Set the dial slightly above your target at the start to account for this drift, and re-verify flow mid-sample for long-duration runs. Also check for tubing kinks, a loose cassette seal, or a clogged inline filter. The constant-flow motor helps, but it has limits under high-particulate conditions.
What does it cost to rent the Allegro 9801-88 T-101?
$45/day and $115/week. For AHERA asbestos clearance projects, budget separately for cassettes (typically 25mm MCE filters), NVLAP-accredited lab PCM analysis, and chain-of-custody supplies — those costs typically exceed the pump rental on any clearance job.
