Product Description

The Airpura 900-MAX is the double-capacity version of Airpura's industrial fume extractor: two poly prefilters, 40 lb of SuperGas activated carbon (2 x 20 lb), and dual MERV-13 particle filters stacked in a 42" powder-coated steel cabinet. Airflow reaches 850 CFM free flow, and per Airpura the MAX configuration is aimed at larger workspaces and heavier contamination than the standard 900. It still runs on ordinary 115V single-phase power at 2.1 A and rolls on casters at 72 lb.

Who It's For

Per Airpura, the 900 series is intended for welding, machining, and 3D printing workshops; laser engraving and manufacturing facilities; hair and nail salons; and bars, restaurants, cigar lounges, and cannabis consumption lounges — with the MAX aimed at the larger or more heavily contaminated of those spaces. In welding environments, Airpura's material cites fine metal particles from electrodes, wires, and coated metals plus gases such as manganese compounds, ozone, and nitrogen oxides among the contaminants addressed. Pick the MAX when fume generation is continuous, multiple stations share one extractor, or carbon in a single-chamber unit would be exhausted too quickly.

Key Features

  • 40 lb SuperGas activated carbon — two 20 lb filters, double the gas-phase capacity of the standard 900
  • Dual MERV-13 particle filters for fine dust, smoke particulate, and metal fines
  • Dual poly prefilters protect both filter chambers and extend media life
  • Up to 850 CFM free-flow airflow with variable speed control
  • 115V / 60 Hz single-phase, 2.1 A — standard outlet, no dedicated circuit hardware
  • 72 lb on casters in a 42" tall powder-coated steel cabinet

How the Filtration Works

The 900-MAX runs air through two complete filter sets:

  1. Dual poly prefilters intercept coarse dust and debris at each chamber inlet.
  2. Two 20 lb SuperGas activated carbon filters adsorb fumes, VOCs, and odors. Doubling the carbon mass extends the time between changes under heavy load and increases contact with the airstream.
  3. Dual MERV-13 particle filters capture fine particulate — smoke, metal fines, dust — before air returns to the workspace.

Airpura 900 vs 900-MAX

The standard Airpura 900 carries one of each stage — poly prefilter, 20 lb SuperGas carbon, single MERV-13 — in a 27" tall, 52 lb cabinet, with 850 CFM free flow (650 CFM with filters, per Airpura). The 900-MAX doubles the prefilter, carbon, and particle stages in the 42" cabinet. Per Airpura, the MAX is the pick for larger or more heavily contaminated workspaces; the 900 covers single-station shops and lighter, intermittent fume loads.

Filter Replacements

Replacement prefilters, SuperGas carbon filters, and MERV-13 filters for the 900-MAX are available through us — call (302) 496-3554 and we will put together the right set. Replacement timing depends on fume load and run hours, so we are glad to help you build a schedule around your shop's usage.

Warranty & Support

Per Airpura, units in commercial use are covered for parts and labor for 2 years, with labor coverage through year 5 (filters and electrical plugs excluded); residential use carries Airpura's 5-year parts / 10-year labor terms. We are a family-owned authorized Airpura dealer — warranty coordination and application questions go through us at (302) 496-3554.

Shipping

At 72 lb in a 42" cabinet, the 900-MAX ships as heavy freight. Before signing the delivery receipt, inspect the packaging carefully and note any dents, punctures, or crushed corners on the driver's paperwork — noting damage at delivery protects your claim. If anything looks wrong at the curb, call us at (302) 496-3554 before the driver leaves.

Frequently Asked Questions

What exactly does the MAX add over the standard 900?

Double media at every stage: 40 lb of SuperGas carbon versus 20 lb, two MERV-13 particle filters versus one, and two poly prefilters versus one, in a taller 42" cabinet (72 lb versus 52 lb). Airflow and electrical specs are otherwise comparable.

Does it need special power?

No — 115V, 60 Hz single-phase at 2.1 A. It plugs into a standard US outlet despite its capacity.

Is the 900-MAX appropriate for welding fume?

Per Airpura, the 900 series targets welding, machining, and 3D printing workshops, and its material cites fine metal particles and gases such as manganese compounds, ozone, and nitrogen oxides among the contaminants addressed — with the MAX aimed at heavier contamination. Confirm your shop's specific ventilation requirements for your processes.

Does it use HEPA filters?

No — the particle stages are MERV-13, which Airpura pairs with SuperGas carbon for fume and smoke work. If your application needs true HEPA capture, call us to compare Airpura's other series.

How often will I change filters?

Airpura does not publish fixed intervals for the 900 series; it depends on fume load and hours. The MAX's doubled media generally goes longer between changes than the standard 900 under the same load. Call us and we will estimate a schedule for your usage.

How loud is it?

76 dBA on high, per Airpura. Variable speed lets you run quieter between active work periods.

Can one 900-MAX serve multiple workstations?

It rolls on casters and plugs into any standard outlet, so many shops position it between stations. Whether one unit is enough depends on your fume generation rate and room size — call us and we will work through it.
