environmental control, pharma
This is one of the environmental controls in the clean room of a pharmaceutical company. I think it might be the filter of the laminar flow hood. I believe THE stands for à très haute efficacité - is this a HEPA filter?
"Vérification des conditions opératoires
Pressions : vérification ΔP en vitesse de travail
(Filtres THE flux (ΔP max : 20 mm H2 O) :
Pression salle (ΔP: de 3 à 5 mm H2 O) :
Pression préfiltres (ΔP max: 18 mm H2 O) :)"

Par définition [02], on appelle filtre THE ou HEPA filter (High Efficiency Particulate Air filter) un filtre présentant suivant l’ancienne norme militaire américaine MIL-F-51068F ‘Filters, Particulate, High-Efficiency, Fire Resistant’ une efficacité minimale de 99,97 % vis-à-vis d’un aérosol de DiOctyle Phtalate (DOP) monodispersé de 0,3 µm. Cette norme est maintenant remplacée par the American Society of Mechanical Engineers ASME-AG-1 ‘Code on nuclear air and gas treatment’ [03] et par la spécification du département américain de l’énergie (DOE) DOE-STD-3020-2005 ‘Specification for HEPA filters used by DOE contractors’ [04].
[...]
Un filtre de même conception qu’un filtre THE mais disposant d’un médium filtrant conduisant à une efficacité minimale de 99,9995 % vis-à-vis d’un aérosol d’environ 0,1 µm (MPPS) est un filtre à très faible pénétration ou ULPA filter (Ultra Low Penetration Air filter). La norme définit les différentes classes de filtres en fonction des efficacités globales et locales (Tableau 2).

: HVAC = heating ventilation and air conditioning - it's the domain not the name of the filter

Sorry,
strictly speaking it is a
Very High Efficiency Filter and not an HEF :-)

Hi
Can I make it clear, although this is not my area I understood that there is more than one "Very High Efficiency" Filter, this is why I answered as "Very High Efficiency Filter" = filtre tres haute efficacité
High-efficiency particulate air (HEPA) filters and ultra-low particulate air (ULPA) filters
i.e
I understood that an HEPA filter and an ULPA filter were both "very-high efficiency filters".
--------------------------------------------------
Note added at 13 hrs (2009-02-20 08:21:14 GMT)
--------------------------------------------------
So
THE = Very high efficiency filter
this is the literal and exact translation, IMHO.

HEPA stands for High-Efficiency Particulate Air filter and refers to a material rated to trap 99.97% of airborne particles 0.3 microns and larger. The ULPA, Ultra-Low Penetration Air, filter traps even more, 99.99% of particles 0.12 microns and larger.
So, this answers your question about whether this is an HEPA filter and why I said "not necessarily" :-)
