Software for the yard running air scrubbers.

An air scrubber is the unit a rental yard sends when a job has to control what is in the air — mold and asbestos spores on an abatement job, smoke after a fire, drywall and concrete dust on a demolition, or just clean air in an occupied space next to construction. The machine pulls air through pre-filters and a HEPA final stage and either holds a containment under negative pressure or scrubs and recirculates. That sounds simple, and the machines are, but a scrubber fleet is hard to run for different reasons than heavy iron: units go out in packs, run unattended for the length of a containment, come back loaded with whatever they filtered, and live or die by their consumable filters. EquipFlow runs air scrubbers the way the yard that built it runs its fleet — dispatch, billing, maintenance, and return inspection on one record per unit.

Built inside Rental King, right now.

Rental King is a heavy-equipment rental yard in Odessa and Midland, TX. They run air scrubbers, manlifts, forklifts, light towers, generators, compressors, and water trucks on MSA contracts through the Permian Basin — 24/7, oilfield pace. EquipFlow was designed and first deployed inside that yard. Every feature was tested against their live operation before it shipped. The product runs there today.

Air scrubbers are low-glamour, high-volume units, and the money on them leaks in small lines that add up. A machine rents by the day and runs unattended, so a unit left on a finished loss keeps a customer happy and the yard empty-handed when another job is waiting. Filters are the quiet earner and the quiet loss — a unit returned with loaded HEPA media that nobody charged for is margin gone, and a unit re-rented without a fresh filter is a callback. Contaminated machines that skip decontamination become a liability that follows the next customer. When dispatch, billing, maintenance, and inspection all read from one unit record, the yard knows which scrubbers are running, which are overdue back, which need filters, and which need decon before they move. That single-record discipline is what keeps a fast-churning scrubber pack from turning into a pile of guesswork on the shelf.

How EquipFlow handles air scrubbers on the dispatch board.

Air scrubbers go out in packs, not ones — a single containment may need several units plus flex ducting, and a restoration loss can pull a dozen at once. The dispatch board treats each unit as its own line so the yard knows exactly which machines are on which loss, even when a customer holds the same model across three jobs. Ducting and spare pre-filters are the trap: a scrubber sent without the flex collar, the exhaust duct, or the filters the job needs is a return trip, so the dispatcher confirms the ducting and consumable count on the rental record before the truck leaves. Because these units sit running unattended for the length of a containment, the board flags which are past their expected off-rent date so a finished job does not keep a machine parked when another loss is waiting.

Billing air scrubbers — MSA, standby, and site-level tax.

Air scrubbers rent by the day and the week, and they bill while they run unattended — there is no operator and no hour meter ticking, so the rental clock is the calendar, not active use. The customer rate lives on the customer record per equipment class, so a restoration contractor or abatement firm on a master agreement gets the negotiated rate applied automatically on every scrubber the yard sends out. Filters are the line item operators forget: pre-filters and the HEPA final filter are consumables, and a unit returned with loaded filters carries a replacement charge that rides the same invoice as the rental. When units sit through a stop-work order or a clearance-test hold, that idle-but-running time bills as standby on a separate line. Tax follows the delivery-site record, so a contractor working losses in more than one jurisdiction is taxed correctly per site, and invoices post to QuickBooks Online on close.

Maintenance on air scrubbers.

Scrubber maintenance is driven by run hours and by what the unit pulled through it, not by the calendar, because a machine that ran flat-out on a sewage or fire loss needs attention a yard spare never will. The run-hour reading is captured at the return inspection and posts to the unit record, and the maintenance module schedules the next service against real usage. The motor and blower carry the work, so service leans on motor-brush condition, capacitor health, and bearing noise alongside the housing gaskets that keep a unit actually sealed — a scrubber that leaks around its own filter is just a fan. Pre-filters and the HEPA stage are tracked as consumables on the unit record, so the yard knows which machines are due for a filter change and which left contaminated. Work orders, parts, and filter history live on the same record, where a decon or damage charge from a return becomes a repair ticket.

Air Scrubber return inspections.

The return inspection is the yard's control, and on scrubbers it is mostly about what the machine pulled through it. Before a unit goes off rent, the driver runs a mobile-web checklist on a phone — no app install — records the run-hour reading, confirms the unit still pulls air and holds suction, and attaches required photos that cannot be skipped. Scrubber-specific checks matter here: the condition and loading of the pre-filters and HEPA stage, the housing gaskets and latches that let the unit seal, the power cord and plug, the flex ducting and collar, and any sign the machine came off a contaminated job. A unit returning from asbestos, mold, or sewage work gets flagged for decontamination before it touches the next loss. The inspection ties to the rental record before the truck leaves, so a filter-replacement or decon charge has photos and a timestamp behind it.

What you give up running air scrubbers in EquipFlow.

EquipFlow is a web app, so the return inspection needs a signal to load. On a sealed basement or interior loss with no coverage, the driver may not be able to finish the mobile inspection at the site; most yards run it at the yard on return instead, so the filter and decon flags land a little later than ideal. There is no automatic sensing of filter loading or containment pressure today — the yard relies on the run-hour reading and the inspector's eyes, not a live feed from the machine. And the rate logic is built around the day-and-week rental model these units run on; a yard with an unusual billing structure should bring it to the demo so it can be scoped honestly rather than assumed.
