Main features:
- Originally created with 3ds Max 2015.
- Two .MAX files with V-Ray and Standard 3ds Max materials.
- Two .MB files with V-Ray and Standard Maya materials.
- Subdivision modifier is available in the history for .MAX, .MB and .C4D file formats (subdivision iteration 1 is set for all objects). So you can get access to original non-smoothed mesh by deactivating the Subdivision modifier.
- Total number of separate objects is 22. All objects are intelligently named:
AirFilter, BodyLogo, Cable, CheckValve, ConnHose, DrainValve, ExhaustPipe, Labels, Motor, PowerCord, PrGaugeLarge, PrGaugeSmall, PrSwitch, PumpFr, PumpRear, QuickConnect, Regulator, SafetyValve, Tank, UnloadingPipe, WheelLeft, WheelRight.
- Unit system is set to metric (millimeters). Real-world scale.
- All textures and materials are included and assigned.
Textures Formats:
(1 .jpg) 1480 x 800px - for basic render studio
(1 .jpg) 2048 x 1024px - for basic render studio
(1 .jpg) 4096 x 3072px - for basic render studio
(3 .jpg) 4096 x 4096px - for model
- Previews rendered in 3ds Max 2015 with V-Ray 3.50.04.

Special notes:
- .OBJ format is recommended for import in other 3d software. If your software doesn't support .OBJ format, please use .3ds format; .OBJ format was exported from 3ds Max. The geometry for .OBJ format is set to quads
- .MAX files can be loaded in 3ds Max 2015 or higher. In order to use V-Ray rendering setups and materials, V-Ray 3.50.04 or higher is needed. V-Ray shaders and render setups are backwards compatible, so you can use V-Ray 2.0 or higher
- .MB files can be loaded in Autodesk Maya 2015 or higher. In order to use V-Ray rendering setups and materials in Maya, V-Ray 3.10.01 or higher is needed. Maya V-Ray renders are similar to 3ds Max V-Ray rendered previews, but not identical
- .C4D file can be loaded in MAXON Cinema4D R17 or higher. Only standard Cinema4D materials and Standard renderer used. Material reflections are set up using the new Reflectance channel introduced in R16
