SCC1.062 Triplex: Multi-Cut Personal Cyclone (PM1 / PM2.5 / PM4)

The SCC1.062 "Triplex" is the most versatile personal cyclone on the market, capable of simulating three different environmental cuts simply by adjusting the flow rate. It functions as a PM1, PM2.5, or PM4 (Respirable) separator, making it a "Swiss Army Knife" for researchers and industrial hygienists who need to characterize different aerosol fractions without purchasing multiple inlet heads.

Key Benefits

• 3-in-1 Functionality:

  • PM4 (Respirable): 1.05 LPM

  • PM2.5 (Fine Dust): 1.5 LPM

  • PM1 (Sub-micron): 3.5 LPM

• Photometer Integration: Ideal for use as a pre-cut inlet for real-time light-scattering photometers (e.g., SidePak, DustTrak) to validate size-specific mass readings.

• Cost-Effective: One hardware unit covers the entire range of relevant health-related particle sizes.

• Precision Machining: Manufactured from high-grade aluminum to ensure exact internal dimensions and consistent cut-points.

Technical Overview

The Triplex leverages the physics of cyclonic separation where the cut-point ($D_{50}$) is inversely proportional to the flow rate. By characterizing the cyclone across a wide flow range, BGI has validated three distinct operating points. This allows the user to switch applications—from monitoring wildfire smoke (PM2.5) to respirable silica (PM4)—solely by changing the pump setting.

Typical Use Cases

• Aerosol Research: Comparative studies of fine vs. coarse particle fractions.

• Indoor Air Quality (IAQ): Investigating HVAC filtration efficiency (PM1 vs PM2.5).

• Instrument Protection: Pre-filtering inlets for handheld optical particle counters.

• Multi-Hazard Surveys: Workplaces with mixed exposure risks (e.g., welding fumes vs. grinding dust).

Why Choose This Cyclone?

Flexibility is the primary driver. If your monitoring campaign requires shifting between respirable dust compliance (PM4) and general air quality investigations (PM2.5), the SCC1.062 Triplex allows you to adapt instantly. It reduces equipment inventory while maintaining the scientific rigor BGI inlets are known for.
