View Model/Dimensions & Sample Drawings

Applications:

Microelectronic Fabrication, Medical Device Manufacturing, QC Inspection, Sterile Filling & Packaging, Pharmaceutical Processing, Semiconductor Manufacturing

Description:

MDR Series – Modular Hardwall Cleanrooms – vertical HEPA filtered airflow cleanroom providing an ISO 5 / Class 100 condition or better; available in various sizes & configurations. The complete unit features durable modular Hardwall construction, using prefabricated walls with wiring posts every 4’ (on center) for efficient installation. (Other Cleanroom Classes Available).

Filters:

compact self-powered HEPA (High Efficiency Particulate Air) ceiling modules. 70mm filter pack. Minimum efficiency of 99.99% at .3 microns; 600 – 750 CFM, 55 dBA’s,  (ULPA filters available)

Prefilters:

1″ bonded polyfiber minimizes surface-loading. 78 % arrestance – 56-57 ASHRAE.

Airflow:

Average clean air velocity 90 fpm (+/-10 fmp). All measured values within +/- 20% uniformity.

Construction:

  • Modular Walls – available in various thicknesses – Polystyrene core (1 ¾” & 3” walls are most common).
  • Wall Covering – various textures include painted Steel or Aluminum, Laminated woodboard & Vinyl covered.
  • “U” Track – Base / Top cap with “H” wiring posts & pre-formed outside corners – Painted Steel or Aluminum.
  • Cleanroom Doors -1 3/4″ Steel or Aluminum, pre-hung with 2’ x 2’ view glass – standard doors = 3’W x 7’H; (other doors are available including double doors, wider or higher than standard doors & also sliding doors)
  • T-Grid Ceiling system – Anodized or Painted Aluminum – gasketed, Heavy duty 1 1/2″ x 1 1/2″
  • HEPA Fan Filter units, Cleanroom Lights & Cleanroom Ceiling Tile.
  • I-beam support is provided, to allow structural & ceiling support (roof deck available)
  • Cleanroom windows are available – full view or ½ view – safety glass or Polycarbonate

Electrical & Power Requirements:

All electrical components are UL Approved / NEC Electrical Code . Standard 115V, 15 Amp, 1 pH, 60 Hz. Units supplied with harness wiring or electrical panel.

Motor/Blower Assembly:

High efficiency Lo-Pro motors to reduce electrical load. Thermally protected & self-lubricating High capacity metal backward curved impellers within direct drive external rotor motors to reduce wear. Statically balanced to maintain constant airflow. Units sit within ceiling grid.

Lighting:

Recessed fluorescent “cleanroom” type sealed 4 bulb Lighting – 125 ft. candle +/- 20 ft. candles. Plastic prismatic lens cover maximizes light diffusion – Lights are drop-in style, sit within ceiling grid.

Controls:

Solid state, adjustable airflow control, 70-120 fpm, 15A load capacity, switches for motor & lights.
