We study the dimension reduction of instantons over product manifolds with calibrated factors. We first prove an integrability result that relates dimension reduction with curvature conditions. Then we find a topological criterion for bundles over product manifolds to admit instantons that satisfy the aforementioned curvature conditions; in particular, pull-back bundles satisfy this criterion. Consequently, we deduce explicit descriptions for the moduli space of Hermitian Yang--Mills connections, G2-, and Spin(7)-instantons in various contexts, and establish well-behaved compactifications for these moduli spaces when one factor of the product manifold is a hyperk\"ahler surface.
