1
Lasair® Pro Family — Dry room handhelds
Lightweight rechargeable handhelds — built for HVAC validation, ISO 14644 dry room spot-checks (RH <1%), coating-room classification and gigafactory corridor audits.
Lasair Pro 350
Handheld · 50 LPM
50 LPM handheld — twice as fast as the 310 version. Ideal for auditing multiple dry rooms, coating lines and slitting stations in a single shift.
Lasair Pro 5100
Handheld · 100 LPM
100 LPM flow — classify an entire gigafactory in one shift. Built for VinFast- and LG Energy-scale gigafactories where every hour of testing is costly.
2
Lasair® III Family — Trolley premium 0.1 µm
Fixed or trolley, sensitivity from 0.1 µm — catches the smallest metal particles that cause short circuits and thermal runaway in cell assembly.
Lasair III 110
0.1 µm · ISO 1-3
The highest 0.1 µm particle counter — the standard configuration for cell assembly rooms, detecting submicron metal shavings that cause short circuits. Essential for premium batteries like 21700 and 4680 cells.
Lasair III 310B
0.3 µm · 6 channels · ISO 4-5
6 measurement channels (0.3, 0.5, 1.0, 5.0, 10 µm) for coating, drying and calendaring in the gigafactory. Balances sensitivity and cost for 90% of battery applications.
Lasair III 350L
Flow 50 LPM · Gigafactory
50 LPM flow (vs the standard 28.3 LPM) — cuts sampling time by 40% for large-volume battery gigafactories, sampling 20+ locations per ISO 14644-1.
3
IsoAir® Pro Family — Fixed 24/7 dry room
Integrates with FacilityPro FMS with continuous data streaming — 24/7 monitoring of dry rooms (dewpoint <-40°C), coating and slitting, with instant alarms on excursion.
IsoAir Pro-E
Ethernet TCP/IP connectivity
Fixed counter with Ethernet connectivity for new gigafactories with existing cabling. Integrates with FMS via TCP/IP, OPC UA, BACnet for critical coating lines and dry rooms.
IsoAir Pro-Plus
Wireless · Flexible deployment
Wireless for battery dry rooms — no cabling through the moisture barrier required, flexible deployment across large gigafactories, AES-encrypted 2.4 GHz. Saves 70% of cabling cost.
IsoAir Pro
Economical version
Entry-level option for battery pilot, R&D and small-scale ESS projects on tighter budgets. Still delivers PMS reliability at an optimized investment cost.
4
Airnet® II Family — Facility-wide networked sensors
Lowest cost per measurement channel — deploy hundreds of sensors across a battery gigafactory to cover all of slurry, coating, drying, slitting and assembly.
Airnet II 4-channel
4 size channels · Network
4-size-channel particle sensor with centralized network connectivity and the lowest cost per channel — ideal for dense facility-wide deployments in the gigafactory.
Airnet II 2-channel (IIS)
2 channels 0.5 µm + 5.0 µm
Economical 2-channel version — sufficient for coating rooms, drying tunnels and battery warehouses requiring basic 0.5 and 5.0 µm monitoring. About 30% lower cost than the 4-channel.
5
Liquid & AMC — Electrolyte + Solvent monitoring
Particle measurement in electrolyte (carbonate solvent) and AMC monitoring for NMP, DMC, EMC solvents — prevents chemical contamination that causes dendrites and capacity fade.
LiQuilaz® II Series
Liquid · Electrolyte filling
Liquid particle counter dedicated to electrolyte filling — detects micron metal particles in LiPF6, EC, DMC before they enter the cell, preventing short circuits and thermal runaway.
AirSentry® II AMC
Molecular · NMP/DMC/EMC
AMC (Airborne Molecular Contamination) monitoring for NMP solvent in slurry and DMC/EMC in electrolyte — catches ammonia, acid and sulfate contamination at ppt level that causes dendrite formation.
SLS-2000 / SLS-1500
Liquid sampler · Slurry
Particle sampler for NMC, LFP and anode/cathode chemistry slurries — QC raw material before mixing, ensuring a uniform, defect-free coating layer.
Guide by Process Step
How to choose a particle counter by each battery manufacturing process
Each process step in a gigafactory has its own contamination sources and monitoring requirements — choosing the right counter up front prevents thermal runaway and improves yield.
DRY ROOM · ISO 6
Cell Assembly · Electrolyte Fill
Dewpoint <-40°C, RH <1%. The most critical area — a 0.1 µm metal particle can cause a short circuit and thermal runaway.
COATING · ISO 7
Slurry Mixing · Calendaring
NMP solvent vapor, slurry contamination. Requires 0.3 µm particle monitoring and AMC ammonia/acid to protect coating quality.
FORMATION · ISO 8
Module · Pack Assembly
Charging/discharging, module assembly, BMS testing. Lower requirements — prioritizes economy and high sensor density across large halls.
