Why Ransburg Vector AA90 79580 Paint Sprayer has poor atomization and distribution?
- Z
  zparkerAug 17, 2025
  Poor atomization and distribution in your Ransburg Paint Sprayer can occur due to several reasons: a partially clogged or badly worn nozzle (clean it out or replace it), low fluid or shaping air pressure (increase or readjust it), high viscosity (try a nozzle with a narrower fan or smaller orifice), an improper nozzle (try a nozzle with a narrower fan or smaller orifice) or a bent high voltage electrode (straighten or replace the nozzle assembly).

What to do if Ransburg Vector AA90 79580 has persistent nozzle clogging?
- K
  Kerry YoungAug 19, 2025
  If you are experiencing persistent nozzle clogging with your Ransburg Paint Sprayer, it could be due to: paint drying in the nozzle or line (flush lines with solvent after each use), the paint applicator filter being too coarse or damaged (replace or change to a finer screen paint filter), or the paint pigments being too coarse (pre-filter paint and/or use a larger nozzle orifice).

Why Ransburg Vector AA90 79580 Paint Sprayer has orange peel or rough finish?
- C
  campbelljohnAug 22, 2025
  An orange peel or rough finish with your Ransburg Paint Sprayer can be caused by: an evaporation rate that's too fast (use a slower evaporating solvent), poor atomization (see "Poor Atomization and Distribution"), or viscosity that is too high (add solvent or heat).

Why is my Ransburg Paint Sprayer paint wrapping back on operator?
- K
  Kaylee SimsAug 26, 2025
  If paint wraps back on the operator when using the Ransburg Paint Sprayer, this can be due to: poor ground on parts (check that parts are fully grounded, strip workholders), the applicator being held too far from parts (hold applicator closer), insufficient or improperly routed booth exhaust (increase, or adjust direction, change booth filter), or improper spray technique (keep applicator directed at work).

Why Ransburg Vector AA90 79580 Paint Sprayer has poor wrapping around?
- T
  travis96Aug 28, 2025
  Poor wrapping around with a Ransburg Paint Sprayer can result from: poor atomization (see "Poor Atomization and distribution"), excessive exhaust velocity (reduce within code limits), excessive fluid pressure (reduce air pressure to pump), holding the applicator too close to the target (hold applicator further back), paint that's too conductive (consult ITW Ransburg technical assistance), or a poor target ground (check ground integrity from target through support to ground).

What to do if Ransburg Vector AA90 79580 Paint Sprayer paint leaks around the nozzle cap?
- T
  Thomas GrayAug 30, 2025
  If paint leaks around the nozzle cap of your Ransburg Paint Sprayer, it's likely due to a loose nozzle cap (tighten the nut) or a worn fluid seal (replace the seal).

What to do if Ransburg Vector AA90 79580 has excessive surging?
- C
  Connie SmithSep 2, 2025
  Excessive surging in your Ransburg Paint Sprayer can be caused by: a restriction in the pump air line (remove the restriction), insufficient pump capacity (secure larger pump or reduce output), a clogged paint filter (service or replace it), low air volume capacity (check factory air capacity), or a nozzle that is too large (replace with correct nozzle).

What to do if Ransburg Vector AA90 79580 leaks through center of nozzle?
- J
  Jordan WhiteSep 5, 2025
  If your Ransburg Paint Sprayer leaks through the center of the nozzle, it could be due to a loose nozzle cap (tighten nut), improper trigger adjustment (readjust), or a defective or dirty valve seat (flush out or replace as needed).

What to do if Ransburg Paint Sprayer has no paint delivery?
- A
  Antonio OsbornSep 8, 2025
  If your Ransburg Paint Sprayer has no paint delivery, the issue might be a clogged nozzle (blow out nozzle), clogged hose or filters (clean them), or no pressure at the paint pump (if pump air supply is OK, consult pump manual).

Why Ransburg Paint Sprayer paint runs or has poor hiding qualities?
- T
  Tasha WilliamsSep 12, 2025
  If the paint from your Ransburg Paint Sprayer runs or has poor hiding qualities, this may be because: the paint has low solids (use less solvent), the viscosity is low (use less solvent), or the delivery is excessive (use smaller nozzle, wider fan angle, lower pump pressure).
