Airlock calculates negative air machine counts and builds itemized abatement quotes — one tool, built for asbestos and mold crews working the containment, not a desk.
One-time purchase. Runs in your phone's browser — nothing to install, no subscription.
Everything you'd otherwise work out on a notepad or a spreadsheet back at the office.
Enter containment dimensions and a target ACH. Airlock returns volume, required airflow, and exact machine count — derated for HEPA filter loading and duct loss, so the number in the field matches the number on paper.
Labor, disposal, containment materials, air monitoring, and your markup — combined into an itemized quote you can print or screenshot before you're back in the truck.
No login, no account, no signal required once it's loaded. Add it to your home screen and it opens like any other app.
| Without Airlock | With Airlock |
|---|---|
| Machine count guessed from memory or a rule of thumb | Calculated from actual volume, target ACH, and rated CFM |
| Quote built later at a desk, job walk half-remembered | Itemized quote built on-site, while the numbers are fresh |
| Spreadsheet that needs signal or a laptop | Runs offline in any phone browser |
| Filter loading and duct loss estimated by eye | Built-in derate factor, adjustable per job |
Any phone, tablet, or computer with a modern browser — iPhone, Android, doesn't matter. Nothing to install from an app store.
