Porta-Screen® Shaker, 7-Tray Capacity (115v/60Hz)

The PS-4 Porta-Screen is a portable aggregate screening machine designed to provide efficient particle-size separation while requiring less space and weight than a full-size stationary testing screen. The seven-tray configuration provides additional separation capacity for aggregate, soil, and other construction-materials testing while retaining the portability that distinguishes the Porta-Screen line.

Key Features

• Seven screen-tray capacity
• Designed for portable or space-conscious aggregate screening applications
• Compact alternative to larger stationary aggregate testing screens
• Accommodates Porta-Screen screen trays
• Provides mechanical screening for aggregate and other granular materials
• Available in 115V/60Hz and 220V/50Hz configurations
• Screen trays and pan are selected separately

Included Items

Gilson PS-4 Porta-Screen shaker with drive and tray-clamping system. Screen trays and collection pan are not included and should be ordered separately based on the laboratory's required sieve series.

Typical Applications

Aggregate gradation, soil particle-size analysis, asphalt aggregate testing, concrete aggregate testing, quarry QC, DOT materials testing, field laboratory screening, construction-materials testing, and laboratories where a full-size testing screen is impractical.

Lab Manager's Tip

The seven-tray model is useful when your standard gradation requires more sieve cuts than the five-tray Porta-Screen can handle in a single run. Build your tray set around the specifications your lab runs most frequently, and remember to account for the collection pan when planning the stack.
