Fai Instruments s.r.l products

The instrument can work with any sampling inlet (PM10, PM2.5, PM1 ) within the operating flow rate range 0.8 ÷ 2.5 m³/h, on two distinct independent channels. Temperature control of the air flow through one or both the sampling lines, in order to minimize volatile material losses (optional feature). Cooling system for the sampled filters Unloader temperature to assure samples stability (optional feature).

SWAM 5a Dual Channel Monitor inherits the extraordinary versatility of HYDRA Dual Sampler for sampling and revolutionizes the implementation of the mass measurement technique, reaching levels of precision defining it the ideal candidate for automatic reference methods for PMx measurement.

Swam 5A Monitor can work with any sampling inlet (for example: PM10, PM2.5, PM1) within the operating flow rate range 0.8 ÷ 2.5m3/h. Sampling at ambient temperature with measurement of the external temperature and of the temperature near the filter. Sampling on ø 47mm filter membranes, exploitable for further analysis.

In order to understand the pollutants accumulation and, in general, the temporal evolution of all air pollution processes, it is necessary to know the low atmosphere layers dilution properties. To get information about the Planetary Boundary Layer dilution potential you need to monitor a chemically stable compound (Radon) with an emission flow that can be considered constant in the interested space-time scale.

Operating configurations: The system can operate in Standalone configuration or in integrated configuration with SWAM 5a Dual Channel Monitor. Standalone Configuration: Periodical manual setting of the parameters for the estimation of the real mass concentration values. Configuration integrated with the FAI SWAM 5a Dual Channel Monitor: Automatic correction with real mass values supplied by SWAM DC with self-learning procedure.

SILENT Sequential Air Sampler  is a sequential instrument specifically developed for particulate matter collection in indoor environment. To assure extended unattended sampling periods, up to 4 inlets (each one carrying one membrane filter) can be installed in the sequential unit and programmed for cycles in the desired sequence.

A very high quality standard in the PMX Sampling with Multi-Jet Inertial Impactor. Structure: The rotary impactor head is made up of the components showm in the picture.

HSRS High Spatial Resolution Sampler F20 is an ambient air sampler with an operating flow rate of 2 lpm for sampling networks ad high spatial resolution, it is able to accumulate PM 2.5, PM 10 or PST particles on all types of membranes with a diameter of 47 mm. The filter is coupled to the NFC Tag system for quick and easy programming and registration sampled volumes. The Main Board measures flow and controls the pump to maintain a constant flow rate. It can measure the main parameters of environmental conditions (T, P, RH) through dedicated accurate sensors. In addition, the main board stores the last two data of the sampling campaign (maximum 2 months) 1h record and uses a 4G cloud based modem connection system.

The instrument operates at a flow rate of 2.83 l/min (0.1 ft³). The system performs dozens of flow measurements per second to adjust the pump speed and have a constant flow in the optical chamber as environmental conditions change. The quality of the pump control system and the sensors used allows for excellent flow accuracy (less than 3%).
