AIRTECH MAC-60P Modular Air Handling Unit with Antistatic ABS Housing

Overview

The AIRTECH MAC-60P is a compact, modular air handling unit engineered for integration into cleanroom auxiliary systems—including laminar flow hoods, pass-through chambers, garment storage cabinets, and localized containment enclosures. It operates on the principle of unidirectional, filtered airflow generation via a precision-balanced centrifugal blower system, delivering ISO Class 5 (Class 100) compliant laminar or turbulent airflow when paired with appropriate HEPA or ULPA filtration. Its core function is to supply continuously conditioned, particle-free air at a nominal volumetric flow rate of 60 m³/h, maintaining consistent velocity profiles and pressure differentials across downstream applications. The unit is not a standalone cleanroom device but a certified component-level air mover—designed for OEM integration and field-assembled clean environments where space, weight, and energy efficiency are critical constraints.

Key Features

• Antistatic ABS housing (R-type) — imported high-impact, electrostatic-dissipative polymer offering mechanical durability, chemical resistance, and compliance with EN 61340-5-1 for ESD-sensitive environments.
• High-efficiency DC brushless blower — developed by AIRTECH specifically for low-power, low-noise operation; achieves ≤56 dB(A) sound pressure level at full load while consuming ≤30 W.
• Five-step airflow control — integrated digital interface enables discrete selection of five fan speed levels, supporting dynamic adaptation to variable static pressure loads and application-specific velocity requirements (e.g., 0.3–0.5 m/s in horizontal laminar flow configurations).
• Dual-status display panel — real-time indication of selected speed stage and active fault diagnostics (e.g., motor stall, thermal overload, or filter saturation warning via optional sensor integration).
• Modular filter interface — accepts standard 250 × 250 × 50 mm filter cassettes; compatible with both H14-grade HEPA filters (≥99.995% @ 0.3 µm) and fluoropolymer-coated PTFE membranes for ultra-low extractables applications (e.g., semiconductor tool purge lines or analytical sample prep zones).
• Tool-free service design — snap-fit housing panels and accessible filter retention clips enable routine maintenance without disassembly tools; filter replacement time < 90 seconds under GLP-compliant documentation protocols.

Sample Compatibility & Compliance

The MAC-60P is validated for use with particulate-limited air streams in non-sterile and controlled non-classified support zones. While not intended for direct sterile processing, it meets structural and electrical safety requirements per GB 4706.1 (IEC 60335-1), EMC compliance per GB/T 17626 series (IEC 61000-4), and RoHS Directive 2011/65/EU. When installed in systems conforming to ISO 14644-1:2015 Annex B and referenced in cleanroom commissioning reports, the unit contributes to achieving Class 5 airborne particle concentration limits. It supports GMP Annex 1-aligned risk assessments for ancillary airflow components and is routinely specified in pharmaceutical facility upgrade packages requiring documented airflow traceability and component-level calibration history.

Software & Data Management

The MAC-60P operates as a standalone electromechanical module without embedded firmware or network connectivity. All operational parameters—including fan speed selection, runtime hours, and fault log entries—are retained mechanically or via external building management system (BMS) integration through dry-contact relay outputs (optional). For regulated environments, users may connect the unit to validated SCADA platforms using 4–20 mA airflow feedback signals (with external anemometer) or integrate its status outputs into FDA 21 CFR Part 11–compliant electronic logbooks via programmable logic controllers (PLCs). Audit trail generation, user access control, and electronic signature functionality must be implemented at the supervisory system level—not within the MAC-60P itself.

Applications

• Modular clean bench retrofits — replacing legacy AC induction blowers in Class 100 laminar flow workstations to reduce energy consumption by up to 65%.
• Pass-through chamber pressurization — maintaining positive differential pressure (10–15 Pa) between classified and unclassified zones during material transfer.
• Clean garment locker ventilation — providing continuous low-velocity air exchange (6–12 ACH) with HEPA-filtered air to suppress fiber shedding and microbial carryover.
• Microelectronics tool purge subsystems — supplying inert, particle-free air to wafer handling modules where metallic leachables from conventional housings are prohibited (PTFE-filter configuration required).
• Mobile clean pod assemblies — enabling rapid deployment of ISO Class 7 environments in clinical trial labs or biomanufacturing pilot lines.

FAQ

Is the MAC-60P certified as a standalone cleanroom device?
No. It is a component-grade air mover intended for integration into larger clean air systems and requires validation within the final installed configuration.
Can the unit be mounted vertically without performance loss?
Yes. Its blower impeller and bearing assembly are orientation-insensitive; vertical mounting does not affect airflow stability or acoustic output.
What filter standards does the MAC-60P support?
It accommodates EN 1822-1:2019 H14 HEPA filters and ASTM F2091-compliant PTFE membrane filters; filter integrity testing must follow ISO 14644-3 Annex D procedures.
Does the unit include a built-in airflow sensor?
No. Real-time airflow monitoring requires external hot-wire anemometry or calibrated pitot tube integration upstream of the filter outlet.
Is technical documentation available in English with regulatory references?
Yes. Installation manuals, dimensional drawings, and CE/GB conformity declarations—including test reports against IEC 60335-1 and GB/T 17626.2—are provided in English upon request and updated per revision control SOP-ENG-007.
