Floor tiles
 |
Laminated access floor tiles are practical for high-traffic areas and walkways, cafeterias and file rooms that require cleanliness and easy access. Available in ten patterns in subtle colors of gray, beige, ivory and white, the surface of the tiles features a special grade of high-pressure laminate designed for maximum durability and high impact resistance. All product grades have low static generation, comply with National Fire Protection Association guidelines and meet or exceed ANSI and NEMA requirements for high-wear grade of high-pressure decorative plastic laminate.
According to the manufacturer, conductive flooring laminates possess significantly lower surface and volume resistance, allowing for rapid bleed-down of static electricity charges. All conductive components are encapsulated within the surface, preventing them from being a source of contamination.

Flexible workstation
The Ergo-Lift workstation features variable height capability and automatic pre-programmable height settings to increase worker comfort and efficiency while reducing vibration, decreasing contaminants and increasing airflow, according to the manufacturer. Motorized lifters raise or lower the table surface. A control panel mounted on the front of the benchtop frame enables operators to adjust the height setting from 32 inches to 49 inches. The workstations can be constructed from static dissipative laminate, non-static dissipative laminate or steel. The unit's thermally protected lifters are hermetic inside the legs to ensure particle retention and cleanroom compatibility.
