PUF3 - Polyurethane Foam Sampler

Helping you measure the toxic organic compounds in ambient air.

A sampling instrument that enables measurement of particulates and PCBs and PAH present in the air by entrapping them in Polyurethane Foam as per US EPA Method TO9A

Available Model : PEM-PUF 3

A PUF Sampler simultaneously collects suspended airborne particulates as well as traps airborne organic vapors such as Pesticides, Polychlorinated bi phenyls-PCBs, Dioxin, Furan and Polycyclic Aromatic Hydrocarbons(PAHS) etc.

PUF3 - Polyurethane Foam Sampler

Applications :

  • Routine Monitoring by air monitoring networks
  • Compliance Monitoring in industrial areas
  • Vehicular Pollution Monitoring in urban areas
  • Monitoring Stations for ISO Compliance
  • VOC Monitoring
  • Fugitive gas monitoring
  • Chemical, Petrochemical, Paint, Cosmetics etc
  • Demos and Operation Trainings.
  • Evaluative Studies
  • Health Impact Studies

Physical Design Highlights

A PUF Sampler comprises a sampling head; a suction blower; a flow measuring device, a flow control device and an Electronic control Module. All these components and assemblies are housed in a sturdy cabinet.

The sampling head is a dual chambered aluminum container which houses both the filtering systems.

The upper chamber supports the airborne particulate filter media in a circular filter holder.

The lower chamber encompasses a glass cartridge which contains the Polyurethane Foam for vapor entrapment.

This dual chambered sampling module is designed for easy access to both upper and lower media. The threaded lower canister is removable with the cartridge intact for immediate exchange. Filter support screens and module components are equipped with gaskets providing a leak proof seal during the sampling process.

Salient Features :

  • Meets requirements of EPA Method, T09A
  • Accurate electronic volumetric flow control system.
  • Wide flow range of 160 to 280 LPM
  • Time based multiple sampling programs.
  • Data logging for more than one sample runs.
  • User Interface comprising LCD module and keypads for sample run setting.
  • Simple setting up of sampling periods.
  • Compact lightweight brush type blower for PUF 1
  • Ultra-efficient, long life brushless, noiseless blower motor for PUF 2
  • Automatic supply voltage monitoring and shut down facility for preventing instrument damage.
  • Durable Weather-proof high quality anodized / powder coated aluminum cabinet.
