Parallel Particle Impactor, Disposable, Preloaded, Respirable, Plastic, 4 L/min - PVC Filter Overview

Parallel Particle Impactor (PPI), plastic, single-use disposable, four-stage, designed for respirable sampling at 4 L/min. The Parallel Particle Impactor (PPI) provides the closest match to the entire ACGIH/CEN/ISO respirable curve compared to any other sampler available. It is preloaded with four porous plastic disc impaction substrates, one 37-mm, 5.0-um PVC collection filter, and one cellulose support, each.

Features

Collection efficiency precisely matches ISO/CEN 7708:1995 size-selection criteria
- Respirable PPI Samplers meet specifications in the 2013 OSHA NPRM for silica

Consumable with no cleaning or two-way shipping costs

Selection of flow rates available to meet specific applications
- 8 L/min respirable PPI: Enhances sensitivity (for short-term and/or low concentration sampling) using high flow pumps; ideal for proposed lower OSHA PEL for silica
- 4 L/min respirable PPI: Enhances sensitivity and can also be used with personal pumps
- 2 L/min respirable PPI: Standard TWA sampling
- 2 L/min thoracic PPI: Metalworking fluids (NIOSH Method 5524) and thoracic TLV-TWA compounds such as sulfuric acid and cotton dust

Patented disposable PPIs are available pre-assembled with:
- Filter and pre-oiled substrates for chemical analysis
- Pre-oiled substrates only – add a weighed filter for gravimetric analysis

Reusable aluminum PPIs also available

Performance published in Journal of Physics and submitted to OSHA docket on silica
