28.3 L/min From a Bench You Can Move
28.3 L/min From a Bench You Can Move
Large-flow instruments are usually fixed. The B300 keeps the 28.3 L/min pump in a chassis with a 24 V pack, so it can be wheeled to a room, run from battery, and print the record on the spot.
- Seven-inch display — 800 × 480, counts and ISO class visible from a step away.
- Printer — built-in 58 mm thermal, no PC in the loop.
- Six channels — 0.3 to 10 μm, 1 CFM, with the class verdict on board.
The stainless front panel is there for wipe-down, not for appearance: these instruments live in rooms that are cleaned on a schedule.
Turnaround Sampling at 28.3 L/min
Turnaround Sampling at 28.3 L/min
When a line is down and the room has to be re-qualified before it restarts, sampling speed is the whole schedule. At 1 CFM the ISO 14644-1 volume arrives in a fraction of the time a 2.83 L/min instrument needs.
- Flow — 28.3 L/min ± 5%, from mains or the 24 V / 6,000 mAh pack, four hours.
- Typical use — Grade C and D classification, facility qualification, turnaround sampling, mobile certification work.
- Weight — 6.8 kg with the pack fitted; two people or a trolley, by design.
Four hours on battery is enough for a shift of point sampling; longer runs stay on mains.
Battery Pack, Printer, 100,000 Records
Battery Pack, Printer, 100,000 Records
The archive holds 100,000 records with the ISO class attached to each, and the printer turns any of them into a signed page without leaving the room.
- Interface — USB 2.0 and RS-232.
- Body — stainless steel front, ABS chassis, 6.8 kg.
- Standards — ISO 14644-1, EU GMP Annex 1, ISO 21501-4; PSL calibration per unit.
The 24 V pack is a swap item, so a second pack extends a shift without waiting for a charge.
FAQ
Because rooms get re-qualified while the services are being worked on. Four hours on the pack means the instrument keeps running through a power interruption, and the room does not have to be re-entered to restart the sample.
At 28.3 L/min the ISO 14644-1 volume for a Grade C or D point arrives quickly — one cubic foot a minute, against a third of that on a 2.83 L/min instrument. When a line is waiting to restart, the sampling rate is the schedule.
Yes, 58 mm thermal, built in. The record can be signed where the sample was taken, and 100,000 records stay in memory for the archive.
A 7″ colour LCD at 800 × 480, with counts and the ISO class verdict visible from a step away. It is not a touchscreen on this model; the touchscreen instruments are the compliance and precision versions.
At 6.8 kg, it can be carried short distances, but it is designed to be wheeled or moved by two. The stainless front and ABS chassis are built to be wiped down, not dropped.
Grade C and D classification, facility qualification and mobile certification work. For Grade A and B points at the limit, the precision models with closed-loop flow are the right choice.
