AIRTECH JAPAN MAC-IIA-101 Small Multipurpose HEPA Filter Unit (class 100, 610 x 610 x 185mm, 99.99％, 10.0m3/min)

1/ Product Overview

The AIRTECH JAPAN MAC-IIA-101 is a compact Fan Filter Unit (FFU) integrating a DC brushless fan with a high-efficiency HEPA filter. It delivers an ultra-clean airflow suitable for ISO Class 5 (Class 100) environments. Its slim profile and light weight allow for easy integration into ceiling grids or mobile filtration frames.

2/ Key Specifications

3/ Applications

Cleanroom ceilings and drop-in modules for semiconductor, optics, or pharmaceuticals.

Filtered air supply to biosafety cabinets, laboratory hoods, and medical analyzers.

Mobile filtration stands for local clean zones.

Assembly lines requiring localized Class 100 air quality.

4/ How It Works

Air enters through a Saran mesh pre-filter that captures coarse particulates. It then passes through the HEPA module, which traps ≥ 99.99 % of particles ≥ 0.3 μm. The DC brushless fan sustains a steady outflow at ~ 0.51 m/s across the discharge face. This laminar sheet of purified air maintains a particle-free zone beneath the unit.

Cleanroom Classification: Class 100 Explained

Class 100 (Fed-Std-209E) equates to ISO 5, permitting no more than 100 particles ≥ 0.5 μm per cubic foot of air. This level of cleanliness is mandatory for precision electronics, sterile drug production, and nanotechnology research. Compliance ensures minimal particulate contamination in critical processes.

5/ Airflow and Velocity

Airflow Rate: 10.0 m³/min (≈ 167 L/s).

Outlet Velocity: ~ 0.51 m/s measured at the filter face.

Delivers uniform, unidirectional flow to sustain local clean zones withoutturbulence.

6/ Motor and Power Requirements

The unit employs a DC brushless motor known for high efficiency and long life. It draws approximately 65 W at full load and connects to a single-phase AC source (100 V 50/60 Hz standard, 200 V optional). Low power demand reduces operating costs.

7/ Noise Level and Power Consumption

Operating at ~ 55 dBA at 1 m from the discharge face, the MAC-IIA-101 is suitable for quiet laboratory or production environments. Power consumption remains around 65 W during maximum airflow, offering an energy-efficient solution.

8/ Dimensions, Weight, and Installation

The 610 × 610 × 185 mm footprint fits standard 600 × 600 mm ceiling grids. Weighing ~ 12 kg, it can be suspended in ceiling modules or mounted on dedicated frames. Simply secure the unit, connect power, and verify positive‐pressure airflow.

9/ Operation Procedures

Energize the unit and allow the fan to ramp up (2–3 seconds).

Confirm the status LED indicates normal operation.

Monitor the discharge velocity periodically with an anemometer.

Maintain unobstructed inlet and outlet clearances for optimal performance.

10/ Maintenance and Filter Replacement

Pre-filter (Saran mesh): clean or replace every 3–6 months depending on dust loading.

HEPA filter: replace every 12–18 months or when differential pressure exceeds 250 Pa.

Inspect gaskets and sealing frames quarterly for air bypass prevention.

11/ Standards, Certifications, and Safety

The HEPA element complies with EN 1822:2009 and achieves ≥ 99.99 % efficiency at 0.3 μm. The housing and motor adhere to RoHS directives, and CE/UL certification is available per configuration. All electrical components meet international safety requirements.

12/ Warranty and Technical Support

Mechanical and electrical components: 12 months.

Full technical documentation, user manuals, and replacement parts provided through QTE Technologies (qtetech.com/en).

13/ Optional Upgrades and Variants

ULPA filter option (≥ 99.999 % @ 0.12 μm) for ISO 4–5 applications.

Alternate airflow models: 5 m³/min, 15 m³/min, and 25 m³/min in the MAC-IIA series.

Custom voltage configurations and integrated control modules available upon request.
