Abatement Technologies PRED-750 Air Scrubber – 750 CFM HEPA Negative Air Machine, Stackable

Abatement Technologies PRED-750 Air Scrubber — 750 CFM Negative Air Machine for Mold, Asbestos, and Lead Containment

The Abatement Technologies PRED-750 (also marketed as the Predator 750) moves 750 CFM through a true HEPA filter rated 99.97% at 0.3 microns. Variable speed control lets you adjust airflow to establish and maintain negative pressure without over-pressurizing the containment zone or creating noise levels that violate healthcare facility policies. The stackable design stores and transports multiple units without additional racks, making the PRED-750 a workhorse for restoration, abatement, and infection-control crews running multiple zones at once.

PRED-750 Airflow and Filtration Specs for Regulated Applications

• 750 CFM at full speed — right-sized for single rooms, residential containment zones, and small commercial spaces; provides 6+ air changes per hour in a 1,500 sq. ft. space at 8-foot ceilings.
• HEPA 99.97% at 0.3 microns — captures mold spores (2–20 microns), asbestos fibers (0.7–90 microns), and lead dust particles; satisfies EPA and OSHA requirements for regulated abatement work.
• Variable speed control — reduces to a lower CFM setting for noise-sensitive healthcare environments while maintaining negative pressure differential; restores to full speed when workers leave the space.
• Stackable, compact footprint — stack up to 3 units per van layer; compact dimensions move through standard residential doorways without disassembly.

Where the PRED-750 Is Deployed

Mold remediation contractors use the PRED-750 as the primary negative-air machine in residential containment zones covering single bedrooms, bathrooms, and crawlspace work areas. Healthcare renovation crews deploy pairs of PRED-750s in ICRA Category II projects adjacent to patient corridors to maintain negative pressure and document HEPA filtration during construction. Water-damage restorers use it during active structural drying to prevent microbial amplification and cross-contamination of unaffected areas. Lead and asbestos abatement contractors operating in pre-1980 residential structures use it to establish regulated negative-pressure work areas required by EPA RRP and NESHAP rules.

PRED-750 vs PRED-1200: Which Predator Air Scrubber Should You Choose?

The PRED-750 and the PRED-1200 share the same 4-stage HEPA filtration architecture and stackable cabinet, but cover different jobsite scopes. The PRED-750 (200–750 CFM, 2.5 amps) is the right tool for residential containment zones, single-room mold remediation, healthcare renovation cells, and any project where you want to daisy-chain multiple units on one 15-amp circuit. The PRED-1200 (300–900 CFM, 3.5 amps) handles larger commercial losses, multi-room category 3 water restoration, and warehouse-scale construction dust control where higher per-unit airflow reduces the total machine count.

Daisy-Chaining PRED-750 Units on a Single Circuit

The PRED-750 draws 2.5 amps or less at full speed, which means up to five units can be daisy-chained on one standard 15-amp circuit using the integrated power-pass-through outlet. This is the practical advantage on residential mold remediation jobs where breaker panels are limited and tripped breakers cost containment integrity. Set each unit's variable-speed dial to match the room volume — typical configurations run two units on low (200 CFM) per bedroom-sized containment for negative pressure, freeing the remaining capacity for active scrubbing zones. Always confirm circuit load with a clamp meter before chaining; older homes with shared circuits may not tolerate the rated draw.

PRED-750 Filter Replacement Schedule and SKUs

The PRED-750 uses a 4-stage filter stack: pre-filter, secondary filter, ASHRAE 95% panel filter, and a true HEPA terminal filter. Pre-filters and secondary filters are consumables — replace them every 40–80 operating hours on dust-heavy jobs (drywall sanding, demolition cleanup) or every 2–3 weeks of typical mold remediation work. The ASHRAE filter typically lasts 3–6 months. The HEPA filter is rated 99.97% at 0.3 microns and should be replaced annually or sooner if pressure differential drops by 25% from baseline. Always pre-filter aggressively in dirty environments — pre-filter cost is negligible compared to a $300+ HEPA filter loaded with construction dust.
