FAQ
F.A.Q.
General / Safety
Is the ozone level produced by the machine compliant with OSHA/NIOSH occupational‑exposure limits?
Yes. When the ozone feature is not activated, background ozone is well below the 0.1 ppm OSHA PEL. The user‑operated ozone mode is locked out for occupied spaces.When the Ozone is activated for decontamination purposes, the Ozone level can reach > .3ppm. PPE must be worn and only trained HAZMAT personnel should operate the machine.
What personal‑protective equipment (PPE) is required while the ozone cycle is running?
There should be no reason to enter the space while decontamination is in process. Operators should wear standard eye protection and, if entering the room before the 3‑hour decay period has expired, a NIOSH‑approved respirator (e.g., N95 or higher). No PPE is needed after the decay period.
Does the device generate any harmful by‑products (e.g., NOx, formaldehyde) during UV or ozone operation?
The UVC lamps are low‑pressure mercury vapor and produce no NOx. Ozone is generated by UV‑186nm light, not plasma, so no nitrogen oxides or acidic by‑products are not formed.
Can the system be integrated into building‑management system?
Yes. The units run on standard wall voltages that can be wired into HVAC control panels for automated start/stop and status monitoring.
Is the equipment certified for use in clean‑room or ISO‑14644 environments?
The core filtration (HEPA H14) meets ISO‑14644‑1 Class 5 requirements. The unit can be commissioned for clean‑room use when operated without the ozone feature.
F.A.Q.
Engineering / Installation
What are the power requirements (voltage, frequency, phase) for each model?
All models operate on 110‑240 V, 50/60 Hz, single‑phase. The 1000‑CFM and larger units draw up to 1.6 kW; the 500‑CFM unit draws <1 kW.
Can the units be hard‑wired or must they be used with a standard plug?
Yes, with a small modification
What is the recommended duct size for the optional positive/negative pressure connections?
This is machine dependent and should match the duct diameter listed in their respective specifications.The range is 254 to 406mm (10-16 inch).
How do I verify that the EC‑motor speed controller is functioning correctly?
The speed controller is roughly approximate to total airflow/10. If used for positive/negative pressure environments, adjusting the motor speed to a target pressure differential is the objective vs. specific airflow CFM.
Is there a way to remotely monitor filter‑life and system status?
Yes. The H14 HEPA are rated at roughly 10,000 hours of use. This is monitored with the Run Time hour meter on the machines.
F.A.Q.
Medical / Clinical Use
Can the device be used in operating rooms (OR) without disrupting laminar flow?
When run in “HEPA‑only” mode (ozone off), the unit can be placed in the OR on a medium to low flow setting without without affecting air velocity or particle counts.
What is the effect of UVC inside the machines?
UVC at 254 nm can inactivate microorganisms on exposed surfaces Including the HEPA but does not degrade the filter media.
Is there a certification for use in isolation rooms (e.g., AIIR – Airborne Infection Isolation Rooms)?
The system meets CDC recommendations for AIIR when configured for negative pressure, with ≥12 ACH (air changes per hour) and HEPA filtration.
How does the system handle bio‑aerosols from COVID‑19, influenza, or TB?
HEPA H14 filters capture ≥99.9995 % of particles ≥0.3 µm; the UVC component inactivates viral RNA. Combined, the system reduces viable airborne pathogens to below detection limits within a single air‑exchange cycle.
Can the machine be used in neonatal intensive care units (NICU) where ozone exposure is a concern?
The ozone feature must be disabled. “HEPA‑only” mode or the HEPA only (Green) devices are safe for NICU environments and can be run continuously to maintain low particle counts.
F.A.Q.
Commercial / Remediation Use
Is the unit suitable for mold remediation in schools or office buildings?
Yes. The combination of HEPA filtration, UVC, and optional ozone (used only when spaces are vacant) effectively kills mold spores and degrades mycotoxins.
What is the recommended dwell time for ozone treatment of a 1,200 ft³ room?
For a full 100 % ozone concentration (> 3ppm), a 3 hour cycle is sufficient for most surface resident pathogens. Mold and “new building sickness” issues (TVOC) may require more time.
Can the device be used to decontaminate HVAC ducts?
A portable kit is available that attaches the unit’s inlet/exhaust, allowing direct circulation through ductwork for 1–2 hour passes.
Does the system remove VOCs and chemical odors?
Yes, the HEPA filter captures particulates; the activated‑carbon pre‑filter (optional) adsorbs many VOCs. For strong odors, the ozone cycle can oxidize organic compounds.
What is the noise level (dBA) at maximum flow?
500‑CFM model: 55 dBA; 1000‑CFM model: 62 dBA at maximum flow. Noise can be reduced by 10 dB using the low‑speed “quiet” setting.
F.A.Q.
Maintenance / Operations
How often must the HEPA filter be replaced in a high‑traffic clinic?
Typical service life is 10,000 hrs of continuous operation or when pressure‑drop reaches > 1 in. wg.
What cleaning procedure is recommended for the external housing and control panel?
Wipe with a damp, low‑pH cloth. Do not use abrasive cleaners or solvents that could damage the housing. If the machine has been in a highly infections or poisonous environment, use Ozone to decontaminate the inside and outside of the machine. In other words, the machine can self clean.
Can the filter be serviced without shutting down the whole unit?
The pre filter features a “hot‑swap” filter housing so the motor continues to run while the filter is changed, preventing loss of pressure. The HEPA requires that the machine be powered down.
Are there spare‑part kits for the UVC lamp and ballast?
Yes. OEM kits include replacement lamps and ballast if required.
What is the recommended schedule for full‑system calibration?
Annually. Calibration includes airflow verification, ozone and UVC‑strength test and HEPA filter flow rate.
F.A.Q.
Maintenance / Facility Management
How do I reset the filter‑hour counter after a filter change?
The runtime and Ozone hour meters are not resettable as is required by law in most applications.
What is the warranty period and what does it cover?
All units carry a 4‑year limited warranty covering all parts and labor. Consumables (HEPA, carbon filter, lamps) are excluded.
Can the unit be moved by a single person?
The all models have built‑in caster wheels and are made from Aluminum making them single‑operator portable. Refer to the specification sheets for weights should the units need lifting.
”What
Store in a dry, environment (5–30 °C). Seal the intake and exhaust ports to prevent dust ingress.
How are the remote‑control and key lock operated for each machine?
Each handheld remote is serialized at the factory and only operates one machine. The key‑lock must be turned on to allow the handheld to operate within 30 meters of the machines. All handhelds are the same (serialized to a specific machine) so operation is the same throughout the product line.
