5090 vs 6090 vs 7090 pad grades overview
Direct answer: The four-digit grade on cellulose cooling pads is flute height plus angle sum. This site lists 5090, 6090, 7090 and 7060. Thickness options are 100 mm, 150 mm and 200 mm. Pick grade and thickness on the inquiry; saturation efficiency and pressure drop are given only on the written quotation.
5090, 6090, 7090, and 7060 are cellulose pad grades on this site. Thickness options on the cooling-pads page are 100 mm, 150 mm, and 200 mm. Use cellulose (or flame-retardant cellulose) for evaporative cooling inlets. Plastic honeycomb pads are for odor-control / exhaust-air wash walls and do not use 5090-style paper codes.
The first two digits are flute height: 50 = 5 mm, 60 = 6 mm, 70 = 7 mm. The last two digits are the angle sum: 90 (common 45°/45° or 60°/30°) or 60 (as in 7060, commonly 45°/15°).
Grade comparison
| Grade | Flute height | Angle sum | Notes |
|---|---|---|---|
| 5090 | 5 mm (50) | 90 | Cellulose cooling grade; angles as quoted |
| 6090 | 6 mm (60) | 90 | Cellulose cooling grade; angles as quoted |
| 7090 | 7 mm (70) | 90 | Cellulose cooling grade; angles as quoted |
| 7060 | 7 mm (70) | 60 | Cellulose cooling grade; different angle sum |
Thickness is chosen separately: 100 mm, 150 mm, or 200 mm as quoted. Height × width are cut to the opening.
The four grades
Grade is not chosen from a published saturation table. Saturation efficiency, pressure drop, and fire rating are given on the written quotation for that house opening.
How to choose — steps
- Confirm the duty: evaporative cooling inlet (cellulose / FR cellulose) versus odor-control wash wall (plastic honeycomb — no 5090 codes).
- If you already know thickness, name 100 mm, 150 mm, or 200 mm.
- If you already know the grade, name 5090, 6090, 7090, or 7060.
- Send house length and width, eave height, species and stocking, and country.
- Email sales@ecoharvestx.com for a written quotation.
FAQ
What do the four digits mean?
Flute height plus angle sum. 50/60/70 = 5/6/7 mm flute height. 90 or 60 = angle sum (90 commonly 45°/45° or 60°/30°; 60 commonly 45°/15° as in 7060).
How does 7060 differ from 7090?
Both use a 7 mm flute height. 7090 has angle sum 90; 7060 has angle sum 60. Saturation and pressure-drop figures are not published as a site table — they are stated on the quotation.
How do I choose thickness?
Name 100 mm, 150 mm, or 200 mm if you already know it from a prior design or house standard. If not, send house data and we confirm thickness on the written quotation. This page does not invent cooling-degree differences by thickness.
Why is there no saturation table on this site?
Saturation efficiency, pressure drop, and fire rating depend on the opening and the quoted pad set. They are given on the written quotation, not as a public performance table.
