The 150 LT Long Throw Supply Grille provides effective directional control of large volumes of air flow. Each bar is pivoted, which allows for cutsom air flow.

The 150 Series Single Deflection Supply Grille provides effective directional control of the air stream in one or two directions. The bars are pivoted at the face, giving a uniform, aligned appearance regardless of blade angle setting.

Louvered Face HEPA Diffuser

SSLF-N-2 Chamber Laminar Flow Diffuser

SSLFHFD-T-HC High Capacity Laminar Flow HEPA Diffuser

The HRDP Series Hinged Radial Pattern Diffuser with Filter is similar to the standard model, however, it incorporates an extended plenum and a unique frame designed to accomodate a Gel Seal HEPA or ULPA filter. These high quality filters can be easily removed and replaced from the face of the unit, and incorporate a separatorless 2″ deep media, integral test port and an anodized aluminum gel seal frame.

A-J Manufacturing provides the highest quality HEPA and ULPA Filters currently available as options in our stainless steel laminar flow and radial flow diffusers, or any combination grille, plaster frame, and plenum models in hinged or non-hinged models. Typical applications include hospitals, semiconductor manufacturing, disk drive and compact disk manufacturing, food processing, pharmaceutical production and aerospace manufacturing.

The SSLFHFD Series Laminar Flow HEPA Filter Diffuser with LED utilizes the well-proven and time-tested concept of vertical air mass ‘laminar flow’ technology, with the addition of an LED Alert Light which, when lit, indicates a change of filter is necessary for optimal performance. The SSLFHFD Series produces a non-aspirating, low velocity, uniformly distributed downward moving ‘piston’ of conditioned air. The filters are designed to accomodate a Gel Seal HEPA or ULPA filter, which can be easily removed and replaced from the face of the unit. These high quality filters incorporate a separatorless 2″ (51) deep media, integral test port and an anodized aluminum gel seal frame.

The SSLFHFD MC Series Medium Capacity Laminar Flow HEPA Filter Diffuser utilizes the well-proven and time-tested concept of vertical air mass ‘laminar flow’ technology. The SSLFHFD Series produces a non-aspirating, low velocity, uniformly distributed downward moving ‘piston’ of conditioned air. The filters are designed to accomodate a Gel Seal HEPA or ULPA filter, which can be easily removed and replaced from the face of the unit. These high quality filters incorporate a separatorless 2″ (51) deep media, integral test port and an anodized aluminum gel seal frame.

The SS Hemispherical Diffusers feature an adjustable pattern control technology for delivering high volumes of low velocity air in a radial pattern. Each model is constructed using adjustable blades which allow adjustment of the discharge air pattern. Two versions of this model are available: SS Hemispherical with an optional adjustable face and SS Hemispherical-PERF with a perforated center section. SS Hemispherical diffuser blades hang less that 1″ below the ceiling.

The HRDP Series Hinged Radial Pattern Diffuser has been designed to provide low aspiration and high ventilation rates especially for clean room applications such as research laboratories, animal labs, food processing, hospital rooms and computer rooms. The unique design of solid baffles in an intrusive perforated face can handle large volumes of air with low initial face velocities. The curved face design is pleasing to the eye, without unsightly sharp angles. Engineered design and performance are the result of extensive laboratory testing.

The FRD Model Flat Face Radial Pattern Diffuser with HEPA Filter has been designed to provide low aspiration at high ventilation rates, especially for clean room applications such as research laboratories, animal labs, food processing, hospital rooms and computer rooms. Specially designed internal baffles and a pressure plate produce an excellent radial air pattern that allows large volumes of air to be supplied at low level velocities. The unobtrusive flat face design provides the smooth appearance required for architectural excellence.

The SSEPD Series Perimeter Slot Diffusers are specially designed to provide an air curtain for operating rooms. The SSEPD Series unique slot design creates a continuous curtain of air, angled outwards 5º – 15º, that encloses the operating area and minimizes the possibility of contaminated air entering the surgical area. The double slot design creates a uniform velocity curtain that minimizes entrainment of contaminated air into the curtain air stream. It also creates a wider velocity profile with less turbulence and hence less induction over similar two slot designs. The face design also incorporates longitudinal deflectors that horizontally deflect a small amount of air lengthwise thereby joining sections and corners with a truly continuous curtain, resulting in enhanced isolation of the surgical area.

The SSLFHFD-FP Series “Criti-Clean” Fan Powered Laminar Flow HEPA Filter Diffuser utilizes the well-proven and time-tested concept of vertical air mass ‘laminar flow’ technology. The SSLFHFD-FP produces a non-aspirating, low velocity, uniformly distributed downward moving ‘piston’ of conditioned air. The filters are designed to accomodate a Gel Seal HEPA or ULPA filter, which can be easily removed and replaced from the face of the unit.
