• Collection efficiency precisely matches ISO 7708/CEN criteria adopted in the OSHA final silica rule

• Resusable conductive aluminum

• 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 new lower OSHA PEL for silica
• 4 L/min respirable PPI: Enhances sensitivity and can be used with personal pumps; TWA sampling for > 4 hours
• 2 L/min respirable PPI: 8-hour TWA sampling

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

• Performance published in Journal of Physics and referenced in the OSHA final silica rule
