Overview

The AireGard™ NU-140 generates HEPA-filtered vertical laminar airflow to provide product protection for sterile but non-hazardous drug compounding or non-hazardous work in microbiology and research labs. The DC ECM motor draws air through a pre-filter and propels it through a HEPA filter to create an ISO Class 5 level of air cleanliness inside a work zone surrounded by stainless steel walls and a work surface made of stainless steel with a PVC core. One easily monitors workbench performance through the Aeromax™ control system that visualizes pressure in the internal airflow plenum. The work zone comes standard with cord-pass throughs and fluorescent lighting but can be optionally configured with polycarbonate walls, an IV bar, LED lighting, outlets, and service valves to meet the demands of your pharmacy or lab's workflow. It is the only model that can be fitted with a UV light and sliding window.

Experience a safer work environment with NuAire's innovative, flexible plenum design, harmonized with an ultra-high efficiency DC ECM motor, not only to uniformly distribute downflow air across the supply HEPA filter for laminar airflow in the work zone but also to reduce sound and vibration significantly. This unique system also promotes even filter loading, extending HEPA filter longevity and ensuring your focus stays on your critical work, undisturbed.

Crafted for optimizing aseptic technique, the durable stainless steel walls and work surface, fortified with a PVC core, offer an effortlessly cleanable work zone essential for maintaining pristine conditions. With two standard cord pass-throughs, it's ideal for seamlessly powering TPN Compounding Systems or Thermocyclers for PCR. It is an impeccable primary engineering control in pharmacies or as a sterile air workbench in microbiology labs, ensuring an uncompromised, easily maintainable, clean environment.

Experience ease of use like never before with our Aeromax control system. Designed for simplicity, it uses intuitive multicolored lights to display airflow performance. Plus, should workbench performance deviate from the norm, both visual and audible alarms ensure clarity and quick understanding. Simplify your operations with user-friendly electronic controls.

Experience significant energy savings with our ultra-high efficiency DC ECM motor. Not only does it operate with reduced noise, but its optimal power also prolongs HEPA filter life. This means considerable long-term savings, reducing the total cost of ownership for your pharmacy or laboratory. Dive into a future of eco-friendly efficiency and lasting savings.

Maintenance contracts for NuAire AireGard NU-140 Vertical Laminar Airflow Workstation

A service visit on the NuAire AireGard NU-140 Vertical Laminar Airflow Workstation covers airflow measurement — inflow and downflow velocities — HEPA filter integrity testing, alarm and interlock checks, and the lighting, UV lamp and electrical safety, following the standard the cabinet is certified to.

Every visit includes calibration and performance verification, and closes with a documented maintenance report you can present during an accreditation audit. Spare-parts availability and a guaranteed response time are written into the contract, so a breakdown never leaves a department waiting for an answer.

Containment and clean-air cabinets like the NuAire AireGard NU-140 Vertical Laminar Airflow Workstation are tested at installation, after they are moved or have a filter changed, and at least once a year — the interval NSF/ANSI 49 and EN 12469 set for biosafety cabinets and the usual practice for clean benches and fume hoods.

  • Inflow and downflow velocities measured against the rated values
  • HEPA filter integrity (leak) test
  • Airflow alarms, interlocks and sash checked
  • Lighting, UV lamp and electrical safety tested

Troubleshooting and repair for NuAire AireGard NU-140 Vertical Laminar Airflow Workstation

When NuAire AireGard NU-140 Vertical Laminar Airflow Workstation fails, our engineers start with a structured diagnostic: error codes, electrical and mechanical checks, and a functional test against the equipment’s own specification. That tells us whether the fault is a consumable, a worn part or a board-level failure before any part is ordered.

Straightforward faults are repaired on site so the department loses as little time as possible. Anything that needs a workbench, a full strip-down or a specialised spare part goes to our workshop and comes back only after a complete post-repair test and, where the equipment requires it, recalibration.

Faults we see most often on this type of equipment

On containment cabinets the recurring faults are loaded or damaged HEPA filters, airflow that has drifted out of range, failed airflow alarms, and motor or blower problems.

Troubleshooting

How to troubleshoot NuAire AireGard NU-140 Vertical Laminar Airflow Workstation

Work through these checks before you escalate. They are the same first-line sequence our biomedical engineers run on arrival, and they either clear the fault or narrow it down enough that the intervention starts with the right spare part in the van.

  1. Capture the fault before you touch anything: write down the exact error code or message, the serial number from the rating plate, what the operator was doing and whether the fault clears on a restart.

  2. Check that the sash or front window is at its working height and that the front grille is not blocked by paper, equipment or forearms.

  3. Read the airflow display or alarm: a low-airflow alarm right after start-up usually means blocked grilles or a loaded filter.

  4. Keep the work zone clear and let the cabinet run for its purge time before starting work; if the alarm persists, stop work and have the airflow measured.

  5. If the fault is still there, escalate with the evidence. Send AxiTech the model, serial number, error code and the checks you have already run, and an engineer will come back with a diagnosis, a repair quote and a spare-parts lead time for NuAire AireGard NU-140 Vertical Laminar Airflow Workstation.

What to send us when you report the fault

  • Manufacturer, model and serial number, from the rating plate
  • The exact error code or message, and the screen it appears on
  • When the fault started, how often it occurs and what triggers it
  • A photograph of the display or of the fault, and the last maintenance report

If the fault survives all five steps, stop using NuAire AireGard NU-140 Vertical Laminar Airflow Workstation and open a repair request. Continuing to run equipment through a fault it cannot clear turns a component failure into a board-level one, and on devices used for diagnosis or therapy it puts the result — and the patient — in doubt.

Buying and installing NuAire AireGard NU-140 Vertical Laminar Airflow Workstation

AxiTech supplies NuAire AireGard NU-140 Vertical Laminar Airflow Workstation together with the accessories and consumables it needs to enter service. We handle importation, delivery and installation, then commission the equipment on site so that it is verified against its specification before the first patient or the first sample.

Installation is followed by training for the users and for your biomedical team, warranty registration, and — if you want it — a maintenance contract that takes over the day the warranty ends, so the equipment never spends a period without planned service.
