Parallel Particle Impactor (PPI), Disposable, Respirable, 4 L/min, Filter and Support Pad Not Included, Orange, 25Pk

Part Number:

225-387A

Overview

These plastic Disposable PPI® Samplers feature four impactors arranged in parallel for precise respirable dust sampling at 4 L/min that meet ISO 7708/CEN respirable criteria. Each PPI® is preloaded with four porous plastic disc impaction substrates. Each requires a user-loaded 37-mm filter and support purchased separately. The orange color identifies it as a 4 L/min respirable model. Single use.

Details

Impaction-based respirable model user-loaded Disposable PPI Samplers contain four impactors arranged in parallel that provide the most precise match to the entire ISO 7708/CEN respirable criteria. Listed in OSHA and MSHA Final Silica Rules, PPI Samplers are also ideal for NIOSH respirable dust methods. All Disposable PPI Samplers contain pre-oiled impaction substrates that effectively trap larger particles for sample integrity. Their design eliminates the tipping sample invalidation often experienced with cyclones, saving you time and money. Disposable PPI Samplers are offered for use at 2, 4, or 8 L/min to meet your applications and are available empty or preloaded. Preloaded models are available with filter preweighed by SKC or not preweighed. Preloaded PPI Samplers do not require assembly. The disposable plastic is single use, so no cleaning is required.

Specifications

Performance Profile

Sampling Rate	2, 4, or 8 L/min
Sample Pump	AirChek Series for 2 and 4 L/min, Leland Legacy for 8 L/min
Sample Time	Dependent on method used. Note: SKC tests indicate that a particulate mass of up to 6.8 mg on the four impaction substrates would not affect PPI performance. This amount is equivalent to sampling for 6 hours at 4 L/min in environments where respirable mass concentration is 4.76 mg/m³ and equals 50% of total dust. Some methods specify no more than 2 mg on the filter for analytical reasons. Therefore, SKC recommends that you work with your lab to determine optimum sample times for your unique sampling conditions.
Sample Media	37-mm, 5.0-µm PVC filter Models with preweighed filter: filter preweighed at 70 F ± 3 F and 50% ± 5% relative humidity Use cellulose pad or stainless steel screen for support.
